Abstract

1286691 Fluid-pressure actuators PLASTUND ELASTVERARBEITUNGSMASCHINENKOMBINAT VEB 14 Oct 1969 50414/69 Heading F1P A valve 4<SP>1</SP> for controlling the hydraulic pressure in a line 26 is positioned by a hydraulic or pneumatic differential piston 6 subjected on its smaller face to a constant pressure in a line 16 and on its larger face to pressure via a line 15 connected to three individually actuated piston and cylinders 12 to 14 of increasing fixed strokes h 1 , h 2 , h 3 and connected through two-position solenoid valves 20 to 22 to the line 16; pistons 12 to 14 being actuable individually or in any desired combination whereby piston 6 together with an adjustable screwed sleeve 1 is displaced against a spring 2 located between a plate 3 and the valve 4<SP>1</SP>. Leakage is made up through a valve 24 which also serves to charge the cylinder space above each piston 12 to 14 when at the bottom of its stroke.
