て成る内接歯車式液体機械。 An internal gear with internal teeth and an external gear with external teeth are provided in a cylindrical hole in the main body so as to be eccentric and rotatable with respect to each other, so that the internal gear and the external gear are at their deepest position. Approximately crescent-shaped partition pieces are arranged circumferentially in the space between the internal gear and the external gear facing the meshing position so that the tips of the teeth of both gears slide into contact with both sides. A low pressure region space and a high pressure region space are formed to face each other, and a low pressure port for liquid and a high pressure region are opened and extend in the circumferential direction to communicate with the low pressure region space on the surface where the axial side surfaces of both gears slide. A liquid high-pressure port extending in the circumferential direction and opening is provided to communicate with the space, and the partition piece has a protrusion formed to protrude in the axial direction and is fitted into a groove bored in the surface on which both gears slide. An internal gear type liquid machine, which is fixed in place and has a recessed groove communicating with the high pressure side so that the pressure liquid on the high pressure side acts on the protrusion in a balanced manner in the circumferential direction.
