Abstract

Tribological conditions between the piston and cylinder wall are very important criteria to realize high efficiency and reliability in piston pumps and motors, in particular for swash plate types. In this paper we theoretically analyze the solid contacting forces and power losses under medium- and high-speed operations. Three calculating methods are discussed with regard to cavitation of the fluid film. The effects of piston mass, differences between the male and female pistons, rotating cylinder block types and rotating swash plate types are also considered.
