Patent-family-90611066

The application provides a radial plunger motor and a shell thereof, wherein a first oil inlet and outlet, a second oil inlet and outlet, a first oil drain port and a second oil drain port are arranged on the periphery of the shell; the first oil outlet and the second oil outlet are adjacent to each other in the axial projection of the shell, the first oil outlet and the second oil outlet are positioned on two sides of the first oil outlet and the second oil outlet, and the opening directions of the first oil outlet and the second oil outlet deviate from the opening directions of the first oil outlet and/or the second oil outlet. So set up, through designing the position and the opening direction of first oil drain and second oil drain, can make first business turn over hydraulic fluid port, second business turn over hydraulic fluid port, the direction of connection and the hookup location dispersion of first oil drain and second oil drain to avoid forming the installation and interfere, be favorable to the structural distribution of the inside runner of casing moreover, promote the stability of each runner.
