Abstract

PURPOSE: To improve turning force and flow rate efficiency by providing a rotor housing with a two-node epitrochoid curve and a rotor with an eccentric shaft and an epitrochoid envelope.
CONSTITUTION: A rotor housing 1 with a two-node epitrochoid curve on its inside contour and a trochoid phase gear 6 which revolves by being supported by the eccentric part 5 of an eccentric shaft 4 in the housing 1 through a rotor bearing 3. A rotor 2 with an epitrochoid envelope on its outside contour which engages with a fixed outer gear 8 is also provided. Turning force occurs by continuously varying the space volume of actuation rooms 15W17 by means of the pressure from input holes 27 and 29. On the other hand, pumping operation is enabled by revolving the shaft 4.
