Title:
EQUAL PRESSURIZING DIFFERENTIAL ROTARY PRIME MOVER
Document Type and Number:
Japanese Patent JPH0587040
Kind Code:
A
Abstract:
PURPOSE: To provide a fluid engine of extremely input saving by generating a rotary movement by equally pressurizing the rotor of a vane type fluid cylinder.
CONSTITUTION: The outer casing 6 of a vane type cylinder is formed elliptical so as to make a rotor 5 reciprocate the outer casing 6 relatively linking to the rotating angle of the rotor 5, and vanes 15 and 16 are pressurized equally. As a result, a differential thrust is generated, and the system is composed to convert the generated differential thrust into a rotating movement. Consequently, different from the conventional hydraulic motor, a discharge port is not required, and the movement is generated only in the fluid pressure.
