    Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber. A shaft seal which is disposed on an end portion of the main bearing, on a side opposite to the compression member, abuts on the rotary shaft.

    Abstract: The present invention aims to provide a motor-mounted internal gear pump that is small-sized, less expensive and has high reliability, while utilizing a function of an internal gear pump that is suitable for high head. A motor-mounted internal gear pump has a pump section for sucking and discharging a liquid and a motor section for driving the same. The pump section has an internal rotor having teeth formed around its outer periphery, an external rotor having teeth formed around its inner periphery and a pump casing that accommodates both rotors and has a suction port for sucking a liquid and a discharge port for discharging a liquid. The motor section has a can that composes a part of the pump casing and formed of anon-magnetic material into a thin plate, a rotator arranged at the inside of the can for driving the external rotor or the internal rotor; and a stator arranged at the outside of the can for rotating the rotator.
