HYDRAULIC DEVICE OF THROTTLE GOVERNING OF HYDRAULIC CYLINDER ROD MOTION SPEED Russian patent published in 2003 - IPC

Abstract RU 2211963 C1

FIELD: devices for throttle governing of motion speed of hydraulic cylinder rod. SUBSTANCE: device has hydraulic cylinder with two working spaces, slide valve distributor with outlet windows and working windows of intake and discharge in body whose working member is in form of cylindrical plunger moving in axial direction and having recesses on controlling edges. In this case, distance between controlling edges with cylindrical plunger recesses equals distance between opposite sides of outlet windows and window of admission of slide valve distributor body to provide for throttle governing of working fluid flow to both working spaces of hydraulic cylinder, through outlet windows of slide valve distributor for one working stroke of cylindrical plunger. EFFECT: reduced amount of governing devices. 5 dwg
