摘要： A control device (3) controlling an electric motor (2) is disposed on an axial line of a rotor shaft (30) of the electric motor (2). The control device (3) includes semiconductor switching devices (15) forming a three-phase bridge circuit that controls a current of the electric motor (2) and capacitors (13) that suppresses a ripple component of a current flowing to the electric motor (2). The semiconductor switching devices (15) and the capacitors (13) are provided in pairs for respective arms of the three-phase bridge circuit and disposed concentrically. Hence, impedance across the three-phase circuit controlling a current flowing to the electric motor is reduced. Consequently, not only can ripples be absorbed efficiently but also power efficiency of a driving device can be enhanced.

摘要： In a swash plate type axial piston pump, a swash plate 23 is fixed and supported in a cabinet while being inclined with respect to the center axial line of a rotary shaft 3. A cylinder block 15 having a plurality of cylinders 13 is attached to the rotary shaft 3 so that the cylinder block 15 slides of the rotary shaft 3 in the axial direction thereof and is rotated integrally therewith. Each one end of a plurality of pistons 21 is slidingly engaged with the cylinder 13 and the other end thereof is abutted against the swash plate 23 through a shoe 25. A valve plate 31 having a suction port 33 and a discharge port 35 is disposed so as to be abutted against the inner surface of the cabinet 1 and the bottom the cylinder block 15 so that a suction path 39 and a discharge path 41 in the cabinet 1 are selectively communicated with a pump chamber 14 in each cylinder through the suction port 33 and the discharge port 35. An operating oil is supplied to the sliding portion between the valve plate 31 and the bottom of the cylinder block 15 by a lubrication means. With this arrangement, since the operating oil is positively supplied to the sliding portion being rotated of the swash plate type axial piston pump, the sliding portion is sufficiently lubricated even if the pump is started to thereby prevent the dry state of the pump.

摘要： The solenloid coils 26, 27 of a hydraulic spool valve may be selectively connected in series or parallel by a switch unit 101. The series connection is used during normal control operations, but if the valve spool 4 becomes jammed the unit switches over to the parallel connection. This quadruples the coil current, and the attendantly increased magnetic drive force enables the spool to shear through the contaminant particles entrained in the hydraulic fluid that are causing the jamming.
