Abstract:
PCT No. PCT/NL92/00211 Sec. 371 Date May 18, 1994 Sec. 102(e) Date May 18, 1994 PCT Filed Nov. 19, 1992 PCT Pub. No. WO93/10344 PCT Pub. Date May 27, 1993.A free piston engine having a fluid pressure unit which includes a cylinder and a piston arranged within the cylinder and reciprocating therein between the bottom dead center and the top dead center. The piston includes a plunger-shaped piston extension cooperating with the fluid pressure unit. This fluid pressure unit is equipped with an auxiliary member for moving the piston in a direction to its bottom dead center. This auxiliary member includes a connecting channel adapted to communicate a liquid pressure source with a room in which the plunger-shaped piston extension extends and which room is closed on one side by an axial face of the piston extension which is directed such that, by pressure loading the axial face, the piston is moved towards the bottom dead center. The axial face is formed on a ring slidably arranged on the plunger-shaped extension. The plunger-shaped extension includes a stop adapted for engagement by the ring when it is moved for displacing the piston to its bottom dead center.
