Title:
ELECTRIC MOTOR DRIVING IN-LINE HYDRAULIC SYSTEM
Document Type and Number:
Japanese Patent JPH05122901
Kind Code:
A
Abstract:
PURPOSE: To achieve a compact structure by forming an electric motor and a pump in one piece, increase the cooling effect due to the fluid immersion of a motor, and at the same time apply a device to each type of electric motors. CONSTITUTION: A hydraulic device 10 is constituted of a housing 11, end plates 12 and 13, and an electric motor in the housing consisting of a stator 14 and a rotor 15, vane pumps 20 and 21 are provided outside the end plates 12 and 13, and a shaft 18 is engaged to a rotor 22 of a pump cartridge for operation. The housing 11 has a hydraulic fluid suction hole 11a in the radial direction, and the pumps 20 and 21 suck fluid into the housing 11, when the rotor 15 of the electric motor rotates. Then, the fluid passes through a space 24 into the inner surface of the housing 11 from an area near the stator 14, passes through a path 25 of the rotor 15 and reaches suction paths 26 and 27 located at the end plates 12 and 13, and flows into the vane pumps 20 and 21.
