Title: Motion of the Piston in Piston Pumps and Motors. 3rd Report. Experiments and Theoretical Discussion.
Abstract: Under low speed operation the frictional characteristics of pistons with hydrostatic pads and conventional pistons were experimentally obtained and compared with the theoretical results already reported. The metallic contacting forces under mdium and high speed operation are theoretically given. Finally, the effect of conically arranged cylinder bores on reduction of the radial loads acting on pistons is discussed.
