    摘要： A hydraulic pump, capable of generating a satisfactorily high pressure in a pocket of a static bearing in a region in which a suction side is switched to a discharge side, to prevent the individual contact of sliding surfaces, comprising a driving shaft inclined relatively to an axis of rotation of a cylinder block, a rotary board member rotating unitarily with the driving shaft and linked to a plurality of pistons, a fixed sliding surface on a housing side which slidingly contacts a rear surface of the rotary board member, pressure pockets formed in the sliding surface of the rotary board member correspondingly to the positions of the pistons, pressure passages for introducing a fluid pressure from the interior of cylinders to the pressure pockets via the pistons, and a pressure introducing means for introducing a high-pressure fluid into the pockets, which are moved with the rotary board member along the fixed sliding surface in a position in which a cylinder is switched from a suction side to a discharge side.

    摘要： A diaphragm pump includes a driving mechanism including a crank body fixed to the rotating shaft of a motor, a driving shaft that is fixed to the crank body and inclined, and a driving body rotatably supported by the driving shaft via a bearing member. The driving body includes a shaft portion that stores the bearing member, and an arm portion connected to the deformation portion of a diaphragm. The bearing member includes a first bearing member close to the crank body, a second bearing member spaced apart from the crank body, a shaft hole in which the driving shaft is rotatably fitted, and an oil reservoir formed at a boundary between the first and second bearing members. The shaft hole includes a through hole formed in the first bearing member, and a non-through hole formed in the second bearing member.
