Abstract

1,041,810. Pneumatic single stroke apparatus. F. LEHLE. Dec. 11, 1964, No. 50446/64. Heading F1P. The cylinder 2 of a pneumatichydraulic unit has a piston 5 displaceable therein and is surrounded by a concentric annular chamber 1 containing a membrane 9 which divides the chamber into a liquid filled chamber 10 communicating through an adjustable throttle valve 14 with the cylinder space 8 to the left of the piston 5, and into a gas chamber 11 connected through a valve 16 either to a source of compressed air or to atmosphere. In operation with the valve 16 in the position shown, compressed air is supplied to the cylinder space 7 to the right of the piston 5, whereby the piston moves to the left against the resistance of the liquid in the space 8 being forced to flow through the throttle valve 14 to the chamber 10. The chamber 10 thereby expands expelling air from the chamber 11 through the valve 16. When the valve 16 is operated to return the piston 5, compressed air enters the chamber 11 thereby acting on the membrane 9 to force liquid from the chamber 10 back into the cylinder space 8.
