摘要: front page image
(EN) A cylinder (275-279,13,13C,13E,13G) is configured into a bottomed tubular form and includes an inner peripheral wall (752b,132a), an inner bottom wall (751b,131c,191), an outer peripheral wall (752a,762a,772a,782a,792a,132b) and an intake hole (752c,141) and a discharge hole (752d,142). The inner peripheral wall (752b,132a) slidably guides the plunger (271,51). The intake hole and the discharge hole communicate between the inner peripheral wall and the outer peripheral wall. A pump housing (211,11,11B,11D,15,15H,16) includes a cylinder receiving hole (216,111c,151) that includes an inner peripheral wall, into which the cylinder is inserted. A pressurizing chamber (212,14) is formed by the inner peripheral wall and the inner bottom wall of the cylinder and a distal end outer wall (713,515) of the plunger.
