摘要： PROBLEM TO BE SOLVED: To stabilize pump performance by devising a form of a check valve of a reciprocating plunger pump. SOLUTION: A large diameter valve passage 14b opened in an axial end surface in an axial line direction is formed at each of a right and a side ends of a plunger which reciprocates right and left through an eccentric actuation means which is actuated by an internal combustion engine, and the valve passage 14b is communicated with a water suction passage through a small diameter passage 14a. A valve element 51 of a first check valve disposed in the valve passage 14b is formed non-circular in a front view, and the maximum radius of protruded parts 52 radially protruded in at least three directions are set to be a little smaller than the radius to the valve passage 14a, thereby an axial center of the valve element 51 is not deviated from an axial line of the valve passage 14b even when the first check valve is reciprocated.

摘要： PROBLEM TO BE SOLVED: To equalize the pump performance of both left and right reciprocal plunger type pumps to each other. SOLUTION: This sprayer is constituted so that the outer periphery of the plunger 7 reciprocally moving left and right through an eccentric working means from an output shaft 5 of an internal combustion engine is supported freely slidably by a plunger case 8 and lubricant oil is housed in the plunger case 8. A 1st check valve 15 is arranged in a water suction side flow passage 14 formed in each of left and right both side ends of the plunger case 8. Water suction passages 24, a high pressure chamber 26 provided with a 2nd check valve 25 and a communication passage 27 for sending a high pressure liquid by the left and right movement of the plunger 7 are provided in each of cylinder blocks 9a, 9b attached respectively to both left and right sides of the plunger 7. The high pressure chambers 26, 26 in the cylinder blocks 9a, 9b are connected by a high pressure pipe 32 and a sucked liquid is supplied from the longitudinally directional center part of a water suction pipe 31 connecting the left and the right water suction passage 24, 24.

摘要： PROBLEM TO BE SOLVED: To smoothly actuate a plunger of a reciprocating plunger type pump. SOLUTION: The outer periphery of a plunger 7, reciprocating in the lateral direction from an output shaft of an internal combustion engine through an eccentric actuating means, is slidably supported by a plunger case 8, and a lubricant is stored in the plunger case 8. At a longitudinal center part of the plunger 7, a sliding recess portion 19 having a pair of sliding surfaces 19a, 19b orthogonal and opposite to laterally reciprocating motion of the plunger 7 is formed by cutting off. As an eccentric actuating means, the rotating rotor 21 fitting over the output shaft 5 is pivotally supported to a boss portion of a cover element 11 of the plunger case 8 through a bearing 22, and a square- shaped sliding guide element 18 rotatably fitting over an eccentric portion 21a of a tip part of the rotating rotor 21 is slidably fitted in the sliding recess portion 19.
