Title: Hydraulic pressure supplying device
Inventor: MORI SHUNSUKE
IPC: F15B21/14
Filed: 2001-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic pressure supplying device which reduces excess load on the device even if an inexpensive fixed capacity pump is used and preventing the occurrence of cavitation as well. SOLUTION: An accumulator 10 is connected to a fixed capacity hydraulic pressure pump 9 driven by an engine 13 through a duct 16 passing through a restrictor 17 and a check valve 18 installed therein. The duct 16 is connected to a return duct 19 through a 1st and 2nd unload control valves 11, 12. When the accumulated pressure of the accumulator 10 reaches a described pressure, the 1st unload control valve 11 is opened, making the use of said accumulated pressure as a pilot pressure, to unload the hydraulic pump 9, thereby keeps the accumulated pressure of the accumulator 10 fairly constant. In the high speed range of engine 13, the discharge of the hydraulic pressure pump 9 increases, this in turn causes an increase in the differential pressure between the upstream and downstream sides.  The increased differential pressure is utilized as a pilot pressure to open the 2nd unload control valve 12 so as to unload the hydraulic pressure pump 9, hence preventing the increase in an excess load.
