Filed: 1957-09-18
Abstract: 868,939. Valves. INTERNATIONAL BASIC ECONOMY CORPORATION. Sept. 18, 1957 [Nov. 28, 1956], No. 29431/57. Class 135. A valve device for controlling the flow of fluids comprises a shuttle-lift valve 72, Fig. 1, operable by a solenoid 68 to control the flow of pressure fluid to and from a chamber 69 to actuate an auxiliary plunger S which in turn controls the flow of pressure fluid to and from a chamber 118 to actuate a main plunger 34 controlling the flow of pressure fluid between an inlet port 50, Fig. 3, exhaust port 62, and motor ports 58, 62 which may lead to a doubleacting cylinder or two single-acting cylinders. Fluid pressure acts at all times on the lefthand side of the head 130 of the plunger 34 and via passages 94, 121 on the right-hand end of the plunger S. When the solenoid is deenergized. the valve 72 is on its lower seat 120 and assuming the plungers 34, S in the positions shown in Fig. 1, a recess 65 in the plunger S connects the passage 94 with the chamber 118 through passages 95, 114, 116 and also with the chamber 69 through the passage 95, passages 92, 90, 104, open valve seat 108, grooves 110 and a passage 112 to retain the plungers in the positions shown. The port 58 is then connected to pressure and the port 60 to exhaust. On momentary energizing the solenoid the valve 72 is raised to be seated on the seat 108 and unseated from the seat 120. The chamber 69 is then exhausted through passage 112 and a passage 124 whence the plunger S is moved leftwardly to cut communication between the passages 94, 95 and connect the chamber 118 with exhaust through the recess 65 and passages 133, 131. The plunger 34 will then move rightwardly to connect the port 60 to pressure and the port 58 to exhaust. On a further momentary energization of the solenoid, the valve 72 is again raised whence pressure fluid passing the necked portion 38 of the main plunger passes through passage 124, the open valve seat 120 and passage 112 to move the plunger S rightwardly to again connect the right-hand end of the plunger 34 through the recess 65 to the passage 94 and the inlet port 50 to move the plunger 34 leftwardly. A manually-actuated valve 88 with a looselyfitting stem 86 normally allows communication between the passages 92, 90 but in the event of electricity failure or to actuate the plungers without the use of the solenoid it may be seated on a seat 102. The chamber 69 is then exhausted through passage 112, grooves 110, valve seat 108, passages 104, 90 and the leaky stem 86, whence as before the plungers S, 34 will be moved to the left and right respectively.
