Title:
DRIVING DEVICE HAVING DIFFERENTIAL CYLINDER CONNECTED WITH CLOSED HYDRAULIC CIRCUIT
Document Type and Number:
Japanese Patent JPS53118681
Kind Code:
A
Abstract:
The drive has a differential cylinder connected to a closed loop hydraulic circuit, having a hydraulic tank and pump. The volumetric differfence during piston adjustment between the volume on the piston face side (4) and the piston rod side (6) is compensated by a rotary flow divider (11), connected to one of the main conduits (3, 5) between cylinder (1) and pump (2). The main stage (12) of the divider is in the conduit (3) between the cylinder space on the piston face side and the pump. The auxiliary stage (13) is located in a branch conduit (14) between the same cylinder space and the tank (8). Alternatively, the main stage may by in the conduit (5) between the cylinder space on the piston rod side (6) and the pump. The auxiliary stage is in a branch off this conduit.
