Abstract

436,431. Hydraulic presses. REID, W. F., 14, Selwyn Road, Edgbaston, Birming- ham. March 15, 1935, No. 8034. [Class 69 (ii)] An automaticallyoperating valve for use with a hydraulic press filled with low pressure water before the application of high pressure, the filling and exhaust strokes being performed by an auxiliary cylinder or cylinders, comprises a casing A for a valve V provided with ports f, and an internal spring-pressed valve D. During the filling stroke, the suction in the main press cylinder first opens the valve D to exhaust the space above the valve V, which is then lifted off its seat C by the low pressure water which enters at J and passes through H to the main press cylinder. When the high pressure is turned on, it enters at M, closes the valve V, opens the valve D and passes through f, H. When the high pressure is shut off, and M connected to exhaust, the pressure in the main cylinder opens the valve V.
