摘要： PROBLEM TO BE SOLVED: To provide a minute flow rate pump realizing fine flow rate liquid feeding accurately operated. SOLUTION: The minute flow rate pump 10 is a syringe type liquid feeding pump provided with a syringe 12 and a plunger 14 for delivering a liquid in the syringe 12. The plunger 14 is provided with a thick line part 14a having a diameter smaller than an inner diameter of the syringe 12 and a thin line part 14b having a diameter smaller than the thick line part 14a. The plunger 14 is constituted as one plunger with a diameter varied along an axial direction. The volume of the plunger 14 occupying the inside of the syringe 12 is increased by drawing out the plunger 14 to a predetermined direction to deliver the liquid in the syringe 12.

摘要： PROBLEM TO BE SOLVED: To develop technology capable of miniaturizing a force feed pump and of stabilizing a force-feeding flow rate of a material, in a waterproof work construction system for performing the work by force-feeding a waterproof liquid to an objective construction position through a force-feeding line to spray or inject it. SOLUTION: This force feed pump 14 is so structured that plural concentrate solutions A and B constituting the waterproof liquid are individually force-fed to plural force-feeding lines 12a and 12b connected to mixing and injecting common nozzle 15 from force-feeding cylinders 16a and 16b having housed piston heads 19a and 19b formed in plural positions in the axial direction of a reciprocatively driven driving shaft 18. This waterproof work construction system is provided with the force feed pump 14.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection pump for preventing generation of hammering sound by a cam shaft and reducing wear of members. SOLUTION: A helical gear 23 is fitted at an end part of the cam shaft 20 and is rotated with the cam shaft 20. The cam shaft 20 is energized in the direction of the arrow B by driving force that the helical gear 23 receives from a crankshaft of an engine. A disc part 22 is formed integrally with the cam shaft 20 in front of the direction in which the helical gear 23 energizes the cam shaft 20 for a cam 21 and is locked by a washer 25. The disc part 22 is formed coaxially with a journalled part 20a of the cam shaft 20 journalled by a journal 15 and has a larger diameter than that of the cam 21. Sliding area of the disc part 22 and the washer 25 is large and the area of the sliding surface in which the disc part 22 and the washer 25 slide is the same.

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump for an internal combustion engine which has relatively many plungers, a relatively short whole length, and a relatively small mounting area around a cam rotation shaft. SOLUTION: This pump has a cam rotation shaft 1, a plurality of cams 2 arranged on the cam rotation shaft, relatively many plungers 3, and a pump chamber 5 provided for each plunger, and a high pressure fuel passage 10 extending from each pump chamber. Each cam actuates at least two plungers, and all of the plungers are positioned on one side of a plane Q extending through a central line of the cam rotation shaft.

摘要： PROBLEM TO BE SOLVED: To provide a radial piston pump of simple structure in which it is practicable to preclude an impact of a cam shaft in a slide bearing originating from a change in the liquid pressure acting on the cam shaft. SOLUTION: A radial piston pump includes a cylinder in alignment in the radial direction with respect to the rotary shaft of a cam shaft and a piston arranged movably in the radial direction against the force of a spring within the cylinder, wherein the piston is pressed outward in radial direction by the rotational motion of the cam and inward in the radial direction by spring member and has at least one inlet to generate communication with the inlet chamber for a pressure feed medium in a position inside about the radial direction, and the pressure medium is pushed into a discharge chamber by the piston moving outward in the radial direction, and the cam shaft is borne by slide bearings installed on both sides of the cam and driven through a pulling means. A pressure communication path is provided between the discharge region (ring-shaped path 52) and at least one of the slide bearings 20 and 22.
