摘要：A pump device comprising a support member (82; 220; 288; 328; 406, 408; 450;502) having a fitting recess, a movable member (80; 276; 322; 402, 404; 514) which isreciprocated in said fitting recess to suck a working fluid, pressurize the fluid and deliver

the pressurized fluid, and a movement restricting device (1; 210; 228; 244; 252; 298; 338;460; 0) operable to deform a wall (86; 208; 226; 288; 332; 406; 408; 450; 516) at leastpartially defining the fitting recess of the support member, such that the wall is

deformed toward the movable member, for restricting a reciprocating movement of themovable member in the fitting recess, at least when an amount of the pressurized fluidrequired to be delivered by the pump device is smaller than a nominal delivery amount ofthe pump device.
