Disclosed is a vane motor including: a casing including a casing including an inlet port and an outlet port, through which a pressurized fluid comes in or out; a rotor being installed in the casing, turning around a rotational shaft by the pressurized fluid and including a rotor body which has a substantially cylindrical shape and an axis coinciding with an axis of the rotational shaft and a plurality of vanes which is installed in grooves formed on an outer circumferential surface of the rotor body and has a portion protruding from the groove and the portion having a length varied in accordance with a rotational phase, and an inner liner of a cylindrical shape which is installed in the casing and receives the rotor therein, in which a distal end of the vane comes into contact with an inner wall surface of the inner liner while the pressurized fluid is retained therein until the pressurized fluid flowing through the inlet port of the casing is discharged from the outlet port of the casing, and an imaginary rotational axis of the inner liner is spaced apart from a rotational axis of the rotational shaft in a parallel state, but is able to rotate together with the rotor when the rotor turns.

According to the present invention, when the rotor turns, the distal ends of the vanes contact against the inner wall surface of the casing, so that the inner wall surface of the casing and the vanes are worn out, to increase a frequency of replacement and repair and since the energy consumed by the abrasion is decreased and is used to generate the rotational force, the energy converting efficiency of the vane motor is improved.

A high efficiency positive Displacement Heat Machines, for applications such as engines with external heating, Internal Combustion Engines with reduced dirty emissions, heat pumps for ecology clear coolers or heaters, working with air from any source of mechanical energy, thermal processes with approximately constant pressure using an external High and Low Pressure Chambers (HPC and LPC that may be the Atmosphere) that are connecting to a Working Chamber (WC) correspondingly at the end of compression and expansion stages. The disclosed engines and heat pumps operate with displacing at least a part of the WF between said WC and HPC, without changing volume of the WC; with Pulse Pause Modulation of crankshaft speed; with remote expander for engine or compressor for heat pump. The expander or compressor are arranged without transferring mechanical work from another parts of the heat machine. The expander is used as power output from the engine, and the compressor is used as power input to the heat pump.

A pneumatic motor includes a stator having a stator inner wall including a dwell region and a rotor eccentrically disposed within the stator. The rotor is configured to rotate about the axis of rotation and includes a plurality of vanes disposed around the rotor. Each vane of the plurality of vanes is configured to slide within a respective slot formed in the outer surface of the rotor between a fully retracted position and a fully extended position as the rotor rotates about the axis of rotation to maintain contact with the stator inner wall. The stator inner wall has a radius relative to the axis of rotation that is substantially constant within the dwell region so that vanes of the plurality of vanes are in the fully extended position within the dwell region.
