Title: Valve for controlling fluid flow
IPC: B60T15/04
Filed: 1966-09-02
Abstract: 1,124,688. Valves; fluid-pressure brakes. WAGNER ELECTRIC CORP. 2 Sept., 1966 [9 Sept., 1965], No. 39367/66. Headings F2F and F2V. A control valve which may be used to energize vehicle brakes, comprises a housing 2, a pair of application means 26, 42 movable in the housing in response to a manually applied force in one direction to effect the application of fluid pressure supplied thereto through the housing and in the opposite direction to isolate the supplied fluid pressure from the applied fluid pressure, and resiliently urged means 17 for following engagement with one of the application means in the other direction to effect corresponding reduction of only the applied fluid pressure. When the stem 42 is moved to the left, a sealing ring 43 disconnects a space 8 in the housing from atmosphere, a closure member 41 is lifted from a seat 35 to connect the space 8 to a space 28 through bores 36, 31 and 32 and the end 40 of the stem engages the member 26 and displaces it to the left until a closure 29 engages a seat 19 on a spring- loaded piston 17 communicating through a bore 6 with exhaust. In this position of the valve, an inlet port 15 communicates with a motor supply port 16. On reversal of the stem 42 the member 41 is reseated and communication between the ports 15, 16 interrupted. Further movement of the stem 42 to the right now causes the closure 29 to be lifted from the seat 19 and the motor port 16 to be connected with the exhaust bore 6 until the pressure has fallen sufficiently on the area A1-A2 for the spring 21 to re-engage the seat 19 with the closure 29. Further rightward increments of travel of the stem 42 provide correspondingly lower pressures in the supply port 16 which inlet and supply pressures acting on the member 26 provide " feel." In the extreme rightward position of the member 26, a seat 13 prevents inlet pressure from acting on the right-hand face of the member which thus tends to be retained in this position. Movement to the left, however, is assisted by fluid acting on differential areas of the member 26. The member 41 may be biased to its open position by a spring 7 or by differential fluid pressures on the member 26.

Abstract: 940,901. Hydraulic presses. BTR INDUSTRIES Ltd. Nov. 16, 1961 [Nov. 17, 1960], No. 39567/60. Heading B5F. [Also in Division F2] A valve assembly for controlling the supply of low and high pressure fluid to a press comprises a low pressure supply 12 and a high pressure supply 11 controlled by a first valve member 17 and a second valve member 39 respectively. A third valve member 25, actuated by a push rod 23, controls the flow to drain. With the drain valve 25 open, it abuts the valve 17 to hold this valve closed while the high pressure valve 39 is held closed by high pressure in chamber 40. When the rod is retracted the low pressure supply opens the valve 17 which closes the drain valve 25 through the valve spindle 24. The low pressure supply is fed to the press cylinder through the outlet 13 until the press meets resistance which causes the pressure to rise until it is sufficient to open the high pressure valve 39. The high pressure fluid then flows to the press cylinder through the outlet 13 and also acts on the valve member 17 to close the low pressure valve.
