Abstract

A hydraulic pressure generator comprises, on the one hand, an internal-combustion engine (1), of which part (7) of the free piston (3) moves in a cushioning chamber (10), and, on the other hand, a hydraulic pump (2), the piston (14) of which is coupled to an auxiliary piston (24) arranged in the cushioning chamber (10), a spring (26) acting on the auxiliary piston in the opposite direction to that of the pressure in the cushioning chamber (10).
