Title: Small compressor
Inventor: HWANG DONG IL
IPC: F04C18/00
Filed: 1999-04-23
Abstract: PURPOSE: A small compressor is provided to generate a high pressure compressed air in a narrow space, and reduce size and weight. CONSTITUTION: A rotating shaft(32) which rotates within a compressed air tank(31) by a motor, is inserted into a shaft hole(36) of a first housing(35) in such a manner that the rotating shaft rotates with stability. A ring-shaped driving hole(43) is formed at a side of a rotating member(41), and a circular space(44) having at an inner periphery thereof a ring gear(45) is formed at an interior of the rotating member. A second housing(51) to be coupled to the first housing accommodates a circular space(52) contacting the circular space(44). A ring gear(53) is formed at an inner periphery of the circular space(52). Linear gears(62,63) of a rotation suppressing device are engaged with the ring gears so that cam motion is performed with stability in accordance with the rotation of the rotating shaft. Since the ring-shaped driving hole of the rotating member is smaller than a compression chamber, i.e., an interior of the second housing, and larger than a circular vane(56) which is connected to the second housing, an air is compressed by changing volume of the compression chamber according to a cam motion of the ring-shaped driving hole. The compressed air flows toward the circular space, and is gathered within a compressed air tank.
