摘要： [PROBLEMS] Provided are an electric signal input-type capacity control device with the use of which the number of pieces of piping to be placed in a hydraulic device can be reduced, and a hydraulic facility with the capacity control device. [MEANS FOR SOLVING PROBLEMS] A pump facility (20) has two pump units (22, 23), and electric regulators (80, 81) are provided at the pump units (22, 23). In each electric regulator (81, 82), drive oil is supplied to an input port and a proportional solenoid valve (86) switches over the condition of supply of the drive oil to a pilot piston (85). The pilot piston (85) operates a servo switchover valve according to the condition of supply of the supplied drive oil and control the condition of supply of mechanism drive oil supplied to serve mechanisms. A servo mechanism (25, 26) changes the capacity of each pump (22, 23) depending on the condition of supply of the mechanism drive oil. A drive oil passage (110) is formed in each electric regulator (80, 81), and the passage connects the input port to a passage extending between the pump units (22, 23).

摘要： A pump unit casing and a pump apparatus having the same are provided to reduce noise from engaging bolts between pump units and a valve unit by using sound insulation walls. In a pump unit casing, a valve unit(24) is disposed between two pump units(22,23). One end of the casing is locked in the pump unit and the other end is locked in the valve unit. The pump units and the valve unit are engaged with engaging bolts. The pump unit casing includes sound insulation walls covering an engagement member so that noise from engaging bolts of the engagement member is insulated. The sound insulation walls can insulate noise from 2 kHz to 6 kHz.

摘要： A valve plate and a hydraulic system with the same are provided to form two or more pressure discharge holes to prevent discharge of working fluid in the jet flow state and noise, thereby preventing damage of the valve plate. A valve plate includes a suction port(31), a discharge port(32) and two or more pressure discharge holes(33) formed at a portion starting an opening of the suction port with a distance from each other in the rotation direction(A20) of a rotation shaft. One of the pressure discharge holes at an upper part in the piston room movement direction is communicated to a discharge place and the other one at a lower part in the same direction is communicated to the suction port.

摘要： A joystick device (1) is provided including a larger number of proportional control actuators (3a,3b,4) than the prior art thereby enjoying higher operability. Joystick device includes an operation lever (2) having a grip portion provided on a surface thereof with a slide switch substantially T-shaped in section. The slide switch (3a) has a web portion (3aw) connected to an upper surface of a shaft rotatably supported at a lower portion of the operation panel. A magnet (6a) is embedded in a lower surface of the shaft (16). When the operator slides the slide switch, the web portion of the slide switch pivots about the shaft, while the shaft rotates to displace the magnet in accordance with pivotal movement of the web portion. A magnetic sensor (6b) detects a variation in magnetic field intensity in accordance with displacement of the magnet, whereby a voltage proportional to the amount of movement of the slide switch is outputted.

摘要： PROBLEM TO BE SOLVED: To provide a piston motor equipped with a brake retarding device of simple structure. SOLUTION: A brake piston 50 presses a casing side brake disc 52 and a cylinder block side brake disc 51 using the spring force of a spring member 54 so that the cylinder block stops rotating. An oil pressure chamber 53 is formed between the brake piston 50 and casing body 33, and to this chamber 53 the working oil from the pressure port 65 of a brake retarding device 60 is introduced to displace the brake piston 50 toward the other side. A first oil passage 74 is formed between the pressure port 65 and chamber 53, while a second oil passage 75 formed in a plunger 71 is in communication with the first oil passage 74 and a third oil passage 76 leading to inside the casing 31. A ball check valve 80 is installed in the connection part of the first oil passage 74 with the second 75, and the second oil passage 75 is equipped with a multi- stage throttle 85.
