摘要： PURPOSE: To sufficiently enable use even if a vibration control material is not used by attaining vibration reduction and noise reduction of a hydraulic piston pump motor itself. CONSTITUTION: In a hydraulic pump 20, a pair of front pump 21a and rear pump 21b are opposed to each other, and rotary shafts are connected to each other by a pump joint 31 so as to mutually negate vibrations generated according to phases of reciprocating motion of respective pistons. The front pump 21a and the rear pump 21b are variable delivery pumps which have the same constitution and whose swash plate 23a inclines to a driving shaft 22 and inclination is controlled by a servo piston 27a constituting a regulator. Since vibration and a noise generated by the hydraulic pump 20 itself are reduced, they can be directly installed on a bracket 32.

摘要： PURPOSE:To obtain a total delivery control device of a pump which enables two types of maximum delivery by providing a pilot stopper on the backing direction of a pressure compensating pressure receiving part and varying the backing limit of said pressure compensating pressure receiving part by means of a pilot pressure. CONSTITUTION:When a pressure compensating pressure receiving part 5 is backed against a spring 9 by means of a pilot pressure Pi in a condition that a pilot pressure Pic does not act on a plot stopper 20, since the pilot stopper 20 has no force of preventing the backing of the pressure compensating pressure receiving part 5, a servo-piston 12 is moved to a place where it is stopped by a maximum flow regulating stopper 23, obtaining the maximum delivery. When the pilot pressure Pic is introduced into a liquid chamber 18, the pilot stopper 20 is advanced to limit the backing of the pressure compensating pressure receiving part 5. Thereby, the servo-piston 12 is stopped in front of the maximum flow regulating stopper 23, to obtain a different maximum delivery.

摘要： PURPOSE:To prevent errosion of a piston chamber of a piston pump caused at its opening section by main jet flow of oil, by changing the injection angle of main jet flow of oil ejected from a main oil feed port or a slot formed in a valve plate for the purpose of lowering the pump noises. CONSTITUTION:Between a low-pressure port 10 and a high-pressure port 11 of a valve plate 7, there is formed a subsidiary oil feed port 22 communicated to an oil groove 15, the port 22 is communicated to an opening 12 of a piston chamber 2 prior to a main oil feed port 16 which is communicated to the high- pressure port 11 via the oil groove 15. When the subsidiary oil feed port 22 is communicated to the opening 12 of the piston chamber 2, a main jet flow of oil 18 begins to be ejected from the main port 16 along a sliding surface 19. Here, the main jet flow 18 of oil is deflected through a large angle in a direction increasing the injection angle theta by a subsidiary jet flow 23 of oil ejected from the subsidiary port 22 in a direction substantially parallel to the axis of a piston 4. Therefore, it is enabled to prevent errosion by the main jet flow of oil.

摘要： PURPOSE:To facilitate manufacture, by a method wherein a semisherical recessed part having the same size as that of the spherical part at the tip of a piston is formed in a drive flange to which the spherical part is connected, and a cylinder part which is caulked to form a guide slip preventing part is formed therearound. CONSTITUTION:A device sucks and delivers fluid by reciprocating main pistons 3... to which a rod tip spherical part 4 is supported by means of a drive flange 2 through rotation of a drive shaft 1 having the drive flange 2. In this device, a semishperical recessed part 6 slidably engaged with the semisphere of the rot tip spherical part 4 is formed in the end surface on the piston 3 side of the drive flange 2. An outer peripheral groove 13 is formed concentrically to an opening edge 7 of the recessed part 6 is formed to form a cylinder part 9. After the spherical part 4 is engaged with the recessed part 6, the cylinder part 9 is caulked to form a guide slip preventing part 10, and the spherical part 4 is held in a slide state.

摘要： PURPOSE:To reduce the fluidity loss of sucking fluid when the discharging amount of the pump is in an increasing direction and the axial center of a cylinder block is inclined by a method wherein a partitioning wall for limiting the flow path of the sucking fluid is provided in the suction path of the fluid in a casing cover. CONSTITUTION:The partitioning wall 23 for limiting the flow path of the sucking fluid is provided in the suction path 19 for the fluid, which is provided in the casing cover 15 forming a slide guidance surface 16. The location of the end of the partitioning wall 23 at the side opposing to the suction groove 11 provided on a slant plate 14 is determined so that the area of the flow path for the fluid limited by the partitioning wall 23, which is flowed from the suction path 19 into the suction groove 11, is minimized when the axial center 9 of the cylinder block is inclined to an angle in which the discharging quantity of the pump is maximized.
