Abstract

1487294 Hydraulic control circuits SMG SUDDEUTSCHE MASCHINENBAU GmbH 23 April 1975 [23 April 1974] 16830/75 Heading F1P The stroke speed of hydraulic rams 17 is controlled by opening or closing cumulatively solenoid operated valves 14À1-14À4 which are controlled by a series of switches 16. The latter are operated by a slide 13 reciprocated by a ram 15 and controlled by a valve 8. The supply of pressurized liquid is from a pump 1 and an accumulator 4. A valve 5 controls the supply to or from valves 14À1- 14À4. Limit switches 18, which are operated by a member connected to the rams 17, control the sequence of operations.
