A pump (10) includes a housing (11, 12) that has a compression chamber (15) for pressurizing fluid and a fluid passage (20, 21, 22, 31, 41) for guiding fluid into the compression chamber (15). A valve (51, 120) is located midway through the fluid passage (20, 21, 22, 31, 41) for communicating and blocking the fluid passage (20, 21, 22, 31, 41). A solenoid actuator (60) is located on a substantially opposite side of the compression chamber (15) with respect to the valve (51, 120) for operating the valve (51, 120). A regulating member (11, 30, 40, 130, 131, 140) is located between the valve (51, 120) and the solenoid actuator (60) for regulating pressure of fluid in the compression chamber (15) from being applied to the solenoid actuator (60). |
