Filed: 1975-09-22
Abstract: 1488530 Hydraulic control circuits ROBERT BOSCH GmbH 22 Sept 1975 [5 Dec 1974] 38816/75 Heading F1P In a circuit having a valve 19 for controlling a ram 37, a changeover valve 46 which returns liquid to a reservoir 13 and has a control line with a throttle 48 the pressure drop across which moves a slide 53 against a spring 54, and means for controlling the ram 37 independently of the load, a shuttle valve 49 is connected in the control line between the valves 46 and 19. When the valves 19, 21, 22 are as shown, the pressure drop across the throttle 48 holds the valve 46 open and liquid returns to the reservoir 13. If the valve 19 is moved to position 29, and if a load acts on the rod of ram 37, a load pressure acts in lines 36 and 18 which is normally greater than the pressure drop across the throttle 48. Thus, a non-return valve 32 closes. A very small initial flow passes from the ram 37 through line 61, shuttle valve 49 and throttle 48 to line 45. This causes valve 46 to throttle line 45 and the pump builds up pressure. Ball 56 closes seat 59 in valve 49 and oil flows to the ram 37. Because of valve 46 the speed of the ram 37 is independent of load and is controlled by the valve 19. If two of valves 19, 21, 22 are operated the greater load pressure is fed to the valve 46 through line 47 and shuttle valves 49, 51 and the ram with the greater load only is controlled independently thereof.
