<P>PROBLEM TO BE SOLVED: To provide a hydraulic power unit, capable of preventing increase in size by preventing control elements for controlling working fluid which is discharged from a hydraulic pump and supplied to an actuator and/or working fluid which is returned from the actuator to an oil tank from being disposed in a parallel manner. <P>SOLUTION: An oil tank 1 is disposed on one end surface 2A of a manifold 2 to close an opening, a hydraulic pump 4 is disposed within the oil tank 1, and an electric motor 5 for rotationally driving the hydraulic pump 4 is disposed on the other end surface 2B of the manifold 2. The one end surface 2A and the other end surface 2B of the manifold 2 are extended respectively, attachment portions 2C, 2D for attaching pressure sensors 13, 15 as control elements are formed on the extended one end surface 2A of the manifold 2, and attachment portions 2E, 2F for attaching pilot operation check valves 16, 19, pressure reducing valves 17, 20, and electromagnetic direction switching valves 18, 21 as control elements in a stacked manner are formed on the other end surface 2B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
