PURPOSE:To regulate the locus of the top edge of a vane by jointing two vanes integrally and allowing the center of two vanes to turn along the circular orbit including both the center of a rotor and the center of a housing. CONSTITUTION:A vane 3 consists of two vanes 3 and 3' which are joined integrally, forming the opening angle of 180 deg.. A rotor 2 is set in eccentric position in a housing 1. As the vane 3 rotates always in contact with the inner peripheral surface of the housing, the vane 3 makes frequent appearance, in relation to the rotor, and the appearance is restricted by a crank shaft beforehand, so the center P of the vanes 3 and 3' turns in the speed twice of the revolution speed of the rotor 2 along the circular orbit (a) which passes through the center Q of the rotor and the center R of the housing 1. |
