Document Type and Number:
Japanese Patent JP3094032
Kind Code:
B2
Abstract:
A means for receiving and subsequently emptying hydraulic fluid from a hydraulic system is described. It comprises a working cylinder (1) and a supply conduit (8) disposed between a pump and the working cylinder for supplying hydraulic fluid at high pressure within a predetermined interval. According to the invention the means also comprises a receiving cylinder (12) with a piston (19), which on one side defines a liquid space (22) for the receipt of hydraulic fluid from the working cylinder with an emptying pressure essentially lower than said high pressure, the piston (19) on the other side defines a chamber (21) containing gas at low pressure, and a high-pressure cylinder (13), which has a liquid space (28) and a plunger (30) movable therein, said liquid space (28) being connected to said supply conduit (8) to receive and return hydraulic fluid at high pressure therefrom and thereto, respectively. A piston rod (31) is disposed between the plunger (30) and the piston (19) to transmit movements from the plunger (30 ) to the piston (19) and reversed. Furthermore, the area of the piston (19) which is pressure-influenced by hydraulic fluid is essentially greater than the area of the plunger which is pressure-influenced by hydraulic fluid.
