Abstract
Abstract A pulse diverter for directing pneumatic pulses from an inlet alternately to a pair of outlets, the diverter including a piston which at the appearance of each pulse is moved from one terminal position to another to establish a flow path between the inlet and one of the outlets while a control member blocks communication between the inlet and the other outlet and at the termination of each pulse, a drive connection is established between the piston and the control element to move the control element into a position blocking communication between the inlet and the first outlet so that the next pulse will be transmitted to said other outlet after the piston is moved to establish communication between the inlet and said other outlet.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
214 words
A pneumatic pulse diverter comprising a housing having an inlet and two outlets, a control chamber in communication with the inlet, flow paths leading from the control chamber to the respective outlets, a control member comprising a disc mounted in said chamber for movement between a pair of terminal positions in which the control member blocks one or other of said flow paths respectively, a cylinder formed in said housing, the control chamber being formed as a radially enlarged section of the cylinder, a piston in said cylinder on which said disc is displaceably mounted and with which said disc is drivingly connected by opposed springs acting between the disc and the piston, whereby the presence of each of a series of successive pneumatic pulses at the inlet effects movement of the piston to establish a connection between the inlet and one or other of said outlets through the respective flow path while the control member blocks the other flow path, and the release of each pulse causes the driving connection to be established between the piston and the control member to move the control member from one terminal position to the other alternately to block the respective flow paths, whereby successive pulses appearing at the inlet are transmitted alternately to the respective outlets.
Claim 2
Dependent Claim
214 words
A pneumatic pulse diverter comprising a housing having an inlet and two outlets, a control chamber in communication with the inlet, flow paths leading from the control chamber to the respective outlets, a control member comprising a disc mounted in said chamber for movement between a pair of terminal positions in which the control member blocks one or other of said flow paths respectively, a cylinder formed in said housing, the control chamber being formed as a radially enlarged section of the cylinder, a piston in said cylinder on which said disc is displaceably mounted and with which said disc is drivingly connected by opposed springs acting between the disc and the piston, whereby the presence of each of a series of successive pneumatic pulses at the inlet effects movement of the piston to establish a connection between the inlet and one or other of said outlets through the respective flow path while the control member blocks the other flow path, and the release of each pulse causes the driving connection to be established between the piston and the control member to move the control member from one terminal position to the other alternately to block the respective flow paths, whereby successive pulses appearing at the inlet are transmitted alternately to the respective outlets.
Claim 3
Dependent Claim
39 words
A pulse diverter according to claim 1 wherein the piston has two opposed sections operating in opposed cylinder sections respectively and a rod connecting the piston sections, and the outputs communicate with the respective opposed sections of the cylinder.
Claim 4
Dependent Claim
46 words
A pulse diverter according to claim 2, wherein the opposed sections of the piston are sealed at least in the terminal positions of the piston against the cylinder and the opposed piston sections control the communication between the outlets and vent openings formed in the cylinder.
Claim 5
Dependent Claim
35 words
A pulse diverter according to claim 1, wherein at least at one end of the piston there is provided one of a pneumatic, electric and magnetic adjusting drive for altering the stroke of the piston.
