Abstract
Abstract A pressure responsive sequencing valve including a housing having an inlet port and a plurality of outlet ports and a ported primary flow control valve located in said housing between said inlet and outlet ports and being mounted for reciprocation between seated and unseated positions and for step-by-step sequencing in rotary motion to place the valve port in register with a selected housing outlet port. An actuation piston is positioned in the housing between said inlet port and the primary valve and is operatively connected to said primary valve to sequence the primary valve in response to operating line pressure. The actuation piston is connected to a cam mechanism so as to cause the sequencing of the primary valve into register with a second outlet port in response to reciprocating motion of the actuation piston caused by line pressure variations and is operable so that positive actuation and sequencing are achieved before flow can pass through the valve.

Claim 1
Independent Claim
418 words
A sequencing valve automatically responsive to the application and reduction of a pressure comprising: A. a housing having an inlet port and a plurality of outlet ports, B. a valve means in said housing and positioned between said inlet port and said outlet ports and shaped to sealably engage each of said housing outlet ports when in its seated position and to have at least one port therein positioned to be in register with at least one of said housing outlet ports to permit flow therethrough while blocking flow through the remainder of the housing outlet ports when in said seated position, C. means for controlling said valve means for seating, unseating and rotational indexing motion in response to a pressure variation comprising: 1. a support member mounted for reciprocating and rotational motion within said housing for cooperation with said valve means to cause seating, unseating and rotational indexing motion of the valve member therein, 2. a pressure responsive piston member rigidly fixed to said support member, 3. a member fixedly positioned in said housing between said inlet port and said valve means and shaped to define a selectively shaped and positioned aperture therein to sealably receive said piston member as said piston member reciprocates with said support member in response to pressure variations and to cooperate with said piston member to either block flow to said valve means or to define a flow port therebetween when out of register to permit flow therethrough to said piston member, 4. cam means operatively connecting said support member and said housing and operative in response to support member reciprocation to cause said support member, said piston member, and said valve means to rotatably index to place said valve means port into register with a second housing outlet port in response to a pressure reduction and reapplication, and D. means for connecting said valve means control means to the valve means wherein said connecting means is a lost motion connection so that said valve member may move to its seated and indexed position before said piston member comes out of register with said aperture so as to permit flow therethrough and to the said valve means, and so that said support member and said piston member rigidly fixed thereto commence motion together to unseat said valve means while said valve means remains seated so that said support member and said piston member impart a momentum force to said valve means to unseat said valve means when the lost motion is dissipated.
