Title: Opposed piston swashplate engine - with central axial working fluid supply and return, and pistons continuously under pressure
Inventor: DIENER HERBERT
IPC: F01B3/00
Filed: 1976-03-05
Abstract: Engine is basically conventional, with an uneven number of cylinders (7) evenly spaced around the periphery of a cylindrical block (5) and swashplate (9) mounted pistons (8) symmetrically in opposition to one another. However the cylinder block has a hollow spindle (10) projecting into it from one end, with an axial partition dividing it into supply and return passages for the working fluid. Long radial ports (16) at the end of these passages come into line in turn with a corresponding port (18) in the wall of each cylinder, allowing fluid press. to displace the pistons during one half of the cycle, causing rotation, and during the other half allowing the pistons to expel the fluid. The pistons are thus under press. throughout and need no retaining springs. The rotation is transmitted to an axial output shaft keyed to the end of the cylinder block remote from the hollow spindle.
