JPH10141265A - Air compressor by elliptical rotor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a quiet air compressor having good efficiency, in which air sucked from two suction ports is completely squeezed out by the operation of brushes for every rotation of a rotor and pressed out from outlets provided with check valves. SOLUTION: An elliptical rotor 3 rotating internally contacting with a cylindrical housing 9 is provided, and brushes 4, 4' sealed in brush cases 5, 5' keep rotating with their lower ends (which are rounded) pressed to contact with the back surface of the rotor by force of springs 8, 8' respectively. Therefore, the air sucked from suction ports 1, 2 are pressed out through check valves 6, 6' so as to be squeezed out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to an air compressor which continuously compresses gas by an elliptical rotor inscribed in a cylindrical housing and a brush pressed against the rotor. The brush is fan-shaped and sealed in the brush case, and makes a vertical arc by the force of the spring. Its width is the same as that of the rotor and works closely inside the housing.

[Problems to be Solved by the Invention] Currently used ones have problems such as vibration and poor efficiency.

[Means for Solving the Problems] The brushes 4, 4 'which are provided with a rotating elliptical rotor 3 in contact with a cylindrical housing 9 and which are sealed in brush cases 5, 5' are springs 8, 8 ', respectively. The lower end (rounding) continues to rotate while being pressed against the back surface of the rotor by the force of. For this reason, the air entering through the inlets 1 and 2 is pushed out from the exhaust port through the check valves 6 and 6 'so as to be squeezed out. The present invention is an air compressor configured as described above.

[Effect of the Invention] This compressor extrudes exhausted air by the action of a rotor rotating in a housing and a brush pressed against the rotor, so that the compressor is efficient. In addition, it can be applied to gas other than air.

Claims (1)

[Claims] 1. A cylindrical housing 9 is provided, and an oblong rotor 3 inscribed therein is provided. Further, an air compressor constituted by providing brushes 4 and 4 'which are in pressure contact with the brushes and springs 8 and 8' and brush cases 5 and 5 'associated therewith.
