SWASH PLATE SWASH PLATE TYPE PUMP AND CONSTRUCTION MACHINE
경사판식 펌프(10)는, 축 부재(18)와, 축 부재에 보유 지지된 실린더 블록(20)과, 실린더 블록의 실린더실(21)에 이동 가능하게 배치된 피스톤(25)과, 피스톤의 단부에 접속한 슈(26)와, 축 부재가 통과하는 중앙 구멍(51)을 형성하는 내벽면부(IS) 및 축 부재의 회전에 수반하여 회전하는 슈와 접촉하는 접촉면부(CS)를 갖은 경사판(50)과, 축 부재를 회전 가능하게 지지하고 경사판을 수용하는 케이스(15)를 갖는다. 구멍(60)은, 일단이 내벽면부에 개구되고 타단이 접촉면에 개구된 구멍(60)을 마련하고 있다. 구멍(60)은, 피스톤에 마련된 통로(25P)를 통해 실린더실에 통한다.
An object of the present invention is to reduce burden of bleeding air in a swash plate pump. To this end, the swash plate pump (10) according to the present invention has: a shaft member (18); a cylinder block (20) held by the shaft member; a piston (25) disposed movably in a cylinder chamber (21) of the cylinder block; a shoe (26) connected to an end of the piston; a swash plate (50) having an inner wall surface (IS) forming a central hole (51) through which the shaft member passes, and a contact surface (CS) contacting the shoe rotating in association with rotation of the shaft member; and a case (15) rotationally supporting the shaft member and accommodating the swash plate. In addition, provided is a hole (60) of which one end is open on the inner wall surface and the other end is open on the contact surface and which communicates with the cylinder chamber through a passage (25P) provided in the piston.
