Abstract
PURPOSE: To provide a means to supply pressurized fluid with a small solenoid valve by controlling by-pass passage with a solenoid valve to create pressure difference for the operation of a change-over valve.
CONSTITUTION: When the discharge volume of each pump 1 and 31 increase a solenoid valve actuates to open a by-pass passage 37 through its detection by detector. The pressurized fluid introduced into a low pressure chamber 36 from the second pump 31 through a pipe 30, supply passage 29, by-pass passage 27, high pressure chamber 35 and orifice passage 34 in by-passed to a tank via the by-pass passages 37 and 38 and pipes 32 and 9 thereby creating a pressure difference between the upstream and downstream of the orifice passage or between the high pressure chamber 35 and the low pressure chamber 36 to move a valve body 25 to the right connecting the high pressure chamber 35 and a by-pass passage 28 to by-pass the pressurized fluid from the second pump 31 to the tank 8 enabling use of a small solenoid valve.
