Abstract
Abstract A mixing tap comprising a tap body with hot and cold water inlets and an outlet all leading into embossments in a hollow spherical configuration on which a spherical control member is swivelably mounted. The control member has an inner mixing chamber with two peripheral openings which selectively cooperate with the liquid inlet ducts to adjust the hot/cold water mixture according to the inclination of the handle, and a third opening which leads to the outlet duct, a flow-setting valve in the mixing chamber being controlled by screwing the handle. Flexible annular lips integral with the embossments about the inlet ducts, and a flexible tongue fitted around an opening in the tap body through which the handle passes, are pressed by the liquid pressure against the control member to provide fluid-tightness.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
202 words
A manually-adjustable mixing tap of the type comprising a spherical control member fluid-tightly swivelably mounted inside a tap body and carrying a manoeuvring handle comprising screw means for actuating a valve mounted in an inner mixing chamber of the control member, the control member having at least three peripheral openings for the inlet and outlet of liquids into and from the mixing chamber, said tap body having ducts cooperating with and selectively connecting said liquid inlet and outlet openings as a function of the position of the control member, the rate of flow from the mixing chamber being a function of the position of the valve, annular lips carried by the tap body, each annular lip surrounding one of the liquid inlet ducts at a location facing the control member, and a flexible annular tongue disposed in an annular chamber formed between the control member and the tap body, said annular chamber communicating with the liquid inlet ducts and surrounding an opening of the tap body through which said handle passes, said lips and tongue being fluid-tightly applied on the spherical surface of the control member by pressure of the liquids to provide fluid-tightness between the control member and the tap body.
Claim 2
Dependent Claim
202 words
A manually-adjustable mixing tap of the type comprising a spherical control member fluid-tightly swivelably mounted inside a tap body and carrying a manoeuvring handle comprising screw means for actuating a valve mounted in an inner mixing chamber of the control member, the control member having at least three peripheral openings for the inlet and outlet of liquids into and from the mixing chamber, said tap body having ducts cooperating with and selectively connecting said liquid inlet and outlet openings as a function of the position of the control member, the rate of flow from the mixing chamber being a function of the position of the valve, annular lips carried by the tap body, each annular lip surrounding one of the liquid inlet ducts at a location facing the control member, and a flexible annular tongue disposed in an annular chamber formed between the control member and the tap body, said annular chamber communicating with the liquid inlet ducts and surrounding an opening of the tap body through which said handle passes, said lips and tongue being fluid-tightly applied on the spherical surface of the control member by pressure of the liquids to provide fluid-tightness between the control member and the tap body.
Claim 3
Dependent Claim
36 words
A tap according to claim 1, in which the tap body is made of plastic material and said lips are integral with embossments on part of the tap body at an end of each inlet duct.
Claim 4
Dependent Claim
45 words
A tap according to claim 1, in which said tongue is independent of the tap body and has a heel portion, and comprising means disposed in said annular chamber for holding said tongue by pressure on its heel portion against a wall of said chamber.
Claim 5
Dependent Claim
22 words
A tap according to claim 3, in which said tongue is made of plastic material, and said holding means comprises a ring.
Claim 6
Dependent Claim
59 words
A tap according to claim 2, in which the tap body comprises an annular embossment between said annular chamber and said opening for passage of the handle, the spherical control member being held by contact with said annular embossment, with said embossments surrounding the inlet ducts and with a further embossment surrounding the mouth of the liquid outlet duct.
Claim 7
Dependent Claim
65 words
A tap according to claim 1, in which the spherical control member is formed of two pieces of plastic material, the tap body also being formed of pieces of plastic material, and comprising a plate having openings in which are welded the ends of liquid-delivery pipes, said plate being disposed in the tap body with sealing joints interposed between said plate and the tap body.
Claim 8
Dependent Claim
65 words
A tap according to claim 1, in which the tap body includes a piece having a concave generally hemispherical surface provided with an embossment forming a concave hemispherical zone supporting the control member, the liquid-delivery ducts leading into said embossment, and said annular lips of the liquid-delivery ducts each being connected by bars forming a grid through which the liquid of the respective duct flows.
Claim 9
Dependent Claim
55 words
A tap according to claim 1, in which the tap body includes a piece having a concave generally hemispherical surface provided with two embossments at the mouths of the liquid-delivery ducts and supporting the spherical control member, each of said embossments having slots forming a grid through which the liquid of the respective duct flows.
