20 man raft co2 inflation valve

Claim 2

A fluid pressure distributing device comprising a housing having inlet port means, vent port means, and outlet port means, passage means for communicating said port means with each other, first valve means located in said passage means, said first valve means having a first position for preventing communication between said inlet and outlet port means while permitting communication between said outlet and vent port means and a second position for permitting communication between said inlet and outlet port means while preventing communication between said outlet and vent port means, second valve means located in said passage means between said first valve means and said outlet port means, said second valve means having a first position for permitting bidirectional flow between said vent and outlet port means when said first valve means is in its first position and having a second position for permitting only unidirectional flow between said inlet and outlet port means when said first valve means is in its second position, means operatively connecting said first valve means to said second valve means so that movement of said first valve means from its first to its second position will cause movement of said second valve means from its first to its second position, and actuating means for causing movement thereof from said first to said second position.

Claim 3

The structure, as defined in claim 1, wherein said first valve means includes a main valve for controlling flow through said inlet port means, vent valve means for controlling flow through said vent port means, and linking means operatively connected to said main and vent valve for providing concomitant movement thereof.

Claim 4

The structure, as defined in claim 2, wherein said actuating means is operatively connected to said vent valve.

Claim 5

The structure, as defined in claim 3, wherein said actuating means includes a rotatable cam plate fixedly connected at its axis of rotation to said housing and having an eccentric groove with detent means at the ends thereof located in the face thereof, and a follower member located in said groove and fixedly connected to said vent valve for causing movement thereof.

Claim 6

The structure, as defined in claim 4, wherein said groove is formed so as to provide said cam with an initial predetermined nonactuating range of rotation and a subsequent predetermined actuating range of rotation.

Claim 7

A fluid pressure distributing device comprising a housing having an inlet port, a vent port, and two outlet ports, first passage means for communicating said inlet port with said vent port, normally closed main valve means located at one end of said first passage means, normally open vent valve means located at the other end of said first passage means for controlling flow therethrougH, second passage means for communicating said first passage means with said outlet ports, linking means operatively connected to said main and vent valve means for providing concomitant movement thereof, check valve means located in one of said outlet ports, said check valve means having an open position for permitting communication between said outlet ports and a pressure responsive closed position for preventing communication between said outlet ports, lever means operatively connected to said linking means and said check valve means for maintaining said check valve means in said open position when said main valve means is in a closed position and said vent valve means is in an open position and for permitting said check valve means to move to said pressure responsive closed position when said main valve means is in an open position and said vent valve means is in a closed position, and actuating means operatively connected to one of said valve means for moving said main valve means to its open position, said vent valve means to its closed position, and said check valve means to its pressure responsive closed position.

Claim 8

A fluid pressure distributing device comprising a housing having an inlet port, a vent port, and two outlet ports, first passage means for communicating said inlet port with said vent port, normally closed main valve means located at one end of said first passage means, normally open vent valve means located at the other end of said first passage means for controlling flow therethrougH, second passage means for communicating said first passage means with said outlet ports, linking means operatively connected to said main and vent valve means for providing concomitant movement thereof, check valve means located in one of said outlet ports, said check valve means having an open position for permitting communication between said outlet ports and a pressure responsive closed position for preventing communication between said outlet ports, lever means operatively connected to said linking means and said check valve means for maintaining said check valve means in said open position when said main valve means is in a closed position and said vent valve means is in an open position and for permitting said check valve means to move to said pressure responsive closed position when said main valve means is in an open position and said vent valve means is in a closed position, and actuating means operatively connected to one of said valve means for moving said main valve means to its open position, said vent valve means to its closed position, and said check valve means to its pressure responsive closed position.

Claim 9

The structure, as defined, in claim 6, wherein said vent valve means includes an axially movable plunger member located in a bore of said housing, and said actuating means includes a rotatable cam plate fixedly connected at its axis of rotation to said housing, said cam plate having an eccentric groove located in one face thereof with detent means at the ends thereof, and a cross-pin follower having one end thereof located in said groove and the other end thereof fixed to said plunger for causing axial movement of said plunger upon rotation of said cam plate.

Claim 10

The structure, as defined in claim 7, wherein said groove is formed so as to provide said cam with an initial predetermined nonactuating range of rotation and a subsequent predetermined actuating range of rotation.

Claim 11

The structure, as defined in claim 6, wherein said check valve means includes a tilt-type spring loaded poppet valve which is seatable in a valve seat formed in said outlet port, said poppet valve having a stem extending therefrom, and said lever means includes a lever which is pivotally connected to said housing and has one end thereof abutting said valve stem and the other end thereof connected to said linking means, said lever having a first position which tilts said poppet valve off its valve seat to an open position and a second position which permits said poppet valve to be fully seated on its valve seat and to function as a check valve.

Claim 12

The structure, as defined in claim 9, wherein said lever is spring loaded so as to urge it towards its first position.
