装置。 The high-pressure side pump 32 connects the pump chamber 56 with a high-pressure seal 62, an intermediate-pressure seal 64, and a low-pressure seal 66 that maintain the seal of the pump chamber 56 against the reciprocating movement of the reciprocating member 52 that increases and decreases the volume of the pump chamber 56.
A first hydraulic space 70 is provided between the high pressure seal 62 and the medium pressure seal 64, and a second hydraulic space 72 is provided between the medium pressure seal 64 and the low pressure seal 66. The first hydraulic pressure space 70 communicates with the suction port 42 of the high pressure side pump 32, and the pressure of the liquid 12 discharged from the low pressure side pump 14 is regulated by the pressure regulating device 24. sent to the suction port 42 of the high pressure side pump 32,
A pump device characterized in that surplus liquid from the pressure regulating device 24 is supplied to the second hydraulic pressure space 72.
