PURPOSE:To make excellent reliability and durability securable to the promotion of high-speed drive and servo-pumping, by forming a cylinder block of an axial piston pump and a shaft of an electric motor solidly as one body. CONSTITUTION:A cylinder block 11, where a piston 12 of an axial piston pump is housed, is set up in a casing 4, while it is formed solidly with a shaft part 11b of a rotator 2 of the electric motor 1 set up inside this casing 4 likewise. One end of this shaft part 11b is supported on the bearing 21 installed in the casing 4, and the other end is supported on the bearing 20 installed in the casing 4 via the cylinder block. According to this constitution, any loast motion is in no case produced between the rotator 2 of the motor 1 and the cylinder block 11, thus such a pump that is provided with excellent reliability and durability is securable. |
