Abstract
Abstract A valve is disclosed which is operated by means of an externally and radially deflectable sleeve which controls fluid flow by not permitting fluid flow in its undeflected state through a valve body disposed in an internal passage of the sleeve, and permitting fluid flow therethrough in its deflected state by blocking and unblocking valve ports in circumferentially spaced protuberance formed in the valve body member to thus provide the valving function without an operator extending from the ambient region into the valving chamber.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
A valve comprising: a radially deflectable sleeve member having an internal passage formed therein; a valve body member having a valving section disposed within said passage and having circumferentially spaced protuberances formed thereon normally gripped by said sleeve member and in engagement with said passage walls; valving means providing a fluid flow path establishing flow through said valve in response to radial deflection of portions of said sleeve into spaces on said valve member intermediate said protuberances, said deflection causing development of a clearance between said sleeve member and said valve body member including said protuberances to define said flow path, said valving means also arresting flow through said valve by elimination of said flow path defined by said clearance space whenever said sleeve member grips said protuberances.
Claim 2
Dependent Claim
128 words
A valve comprising: a radially deflectable sleeve member having an internal passage formed therein; a valve body member having a valving section disposed within said passage and having circumferentially spaced protuberances formed thereon normally gripped by said sleeve member and in engagement with said passage walls; valving means providing a fluid flow path establishing flow through said valve in response to radial deflection of portions of said sleeve into spaces on said valve member intermediate said protuberances, said deflection causing development of a clearance between said sleeve member and said valve body member including said protuberances to define said flow path, said valving means also arresting flow through said valve by elimination of said flow path defined by said clearance space whenever said sleeve member grips said protuberances.
Claim 3
Dependent Claim
40 words
The valve of claim 1 wherein said valving means includes: a fluid passage means formed in said valve body member including at least one fluid passage formed in said valving section and extending into at least one of said protuberances.
Claim 4
Dependent Claim
44 words
The valve of claim 2 wherein said at least one fluid passage extending into said at least one of said protuberances exits on the surface of said at least one of said protuberances gripped by said sleeve member to define a valving surface thereon.
Claim 5
Dependent Claim
53 words
The valve of claim 2 wherein said valving means also includes another fluid passage means formed in said body defining in part said fluid flow path including a fluid passage extending through said valving section spaced from said protuberances and opening into a clearance space between said sleeve member and said valving section.
Claim 6
Dependent Claim
24 words
The valve of claim 4 wherein said valving section is sealed to said internal passage walls at positions on either side of said protuberances.
Claim 7
Dependent Claim
24 words
The valve of claim 1 further including actuation means selectively actuatable to radially deflect said sleeve member so as to create said flow path.
Claim 8
Dependent Claim
46 words
The valve of claim 6 wherein said actuation means includes a pair of elements engaging said sleeve member periphery axially aligned with said protuberances but circumferentially spaced therefrom and further includes means for causing said elements to move towards each other to cause said radial deflection.
Claim 9
Dependent Claim
25 words
The valve of claim 7 wherein said actuation means further includes means for exerting a magnetic force on said elements to cause said movement thereof.
Claim 10
Dependent Claim
182 words
A valve comprising: a radially deflectable sleeve member having an internal passage formed therein; a valve body member having a valving section disposed within said passage and having at least one protuberance formed thereon normally gripped by said sleeve member in engagement with said passage walls; valving means providing a fluid flow path establishing flow through said valve in response to radial deflection of portions of said sleeve into spaces on said valve member adjacent said protuberance, said deflection causing development of a clearance between said sleeve member and said valve body member including said protuberance to define said flow path, said valving means also arresting flow through said valve by elimination of said flow path defined by said clearance space whenever said sleeve member grips said protuberance, and wherein said valving means also includes a fluid passage means formed in said valve body member including at least one fluid passage formed in said valving section and extending into said at least one protuberance said fluid passage being blocked by said sleeve member gripping said protuberance to arrest flow through said valve.
Claim 11
Dependent Claim
182 words
A valve comprising: a radially deflectable sleeve member having an internal passage formed therein; a valve body member having a valving section disposed within said passage and having at least one protuberance formed thereon normally gripped by said sleeve member in engagement with said passage walls; valving means providing a fluid flow path establishing flow through said valve in response to radial deflection of portions of said sleeve into spaces on said valve member adjacent said protuberance, said deflection causing development of a clearance between said sleeve member and said valve body member including said protuberance to define said flow path, said valving means also arresting flow through said valve by elimination of said flow path defined by said clearance space whenever said sleeve member grips said protuberance, and wherein said valving means also includes a fluid passage means formed in said valve body member including at least one fluid passage formed in said valving section and extending into said at least one protuberance said fluid passage being blocked by said sleeve member gripping said protuberance to arrest flow through said valve.
Claim 12
Dependent Claim
33 words
The valve of claim 9 wherein said fluid passage extending into at least one protuberance exits on the surface of said protuberance gripped by said sleeve member to define a valving surface thereon.
Claim 13
Dependent Claim
56 words
The valve of claim 10 wherein said valving means also includes another fluid passage means found in said body defining in part said fluid flow path including a fluid passage extending through said valving section spaced from said at least one protuberance and opening into a clearance space between said sleeve member and said valving section.
Claim 14
Dependent Claim
27 words
The valve of claim 11 wherein said valving section is sealed to said internal passage walls at positions on either side of said at least one protuberance.
Claim 15
Dependent Claim
24 words
The valve of claim 9 further including actuation means selectively actuatable to radially deflect said sleeve member so as to create said flow path.
Claim 16
Dependent Claim
47 words
The valve of claim 13 wherein said actuation means includes a pair of elements engaging said sleeve member periphery axially aligned with said at least one protuberance but circumferentially spaced therefrom and further includes means for causing said elements to move together to cause said radial deflection.
Claim 17
Dependent Claim
24 words
The valve of claim 14 wherein said actuation means further includes means for exerting a magnetic force on said elements to cause said movement.
