Abstract

PURPOSE:To remove the pulsation at the time of the delivery of operation oil and prevent the generation of abnormal sound and noise by constructing the part between the long radius part and the short radius part of the inner wall face of a cam ring by an inner wall faces indicated by specific functions for keeping the instantaneous delivery amount constant. CONSTITUTION:An intermediate part CF between a long radius part AC and a short radius part FB on an inner wall face 4 of a cam ring 3 is constructed of three inner wall faces CD, DE, and EF. Cam curves for these inner wall faces as cross section shapes are selected as: fCD=(-phitantheta2)/(sin<2>theta<2>)sin<2>theta+R2:fDE= -2phitheta-phiTantheta2+R2:fEF=(phitantheta2)/(sin<2>theta2)sin<2>thet a2-2phitheta- 2phitheta(theta0-theta2)-phitantheta2+R2. Where theta: changed amount of angle from reference line, theta2: fixed angle, theta0:2pi/Z0, Z0: total number of vanes, phi:(R2-R1)/2theta0, R1: short radius, and R2: long radius. This construction permits to keep the instantaneous delivery amount constant, and prevent generations of pulsation and noise.
