| 摘要 |
The invention relates to a hydraulic generator of mechanical pulses meant to generate pulses to a working tool, used for demolitions, in constructions or for shattering, in pits, and representing a working equipment for loaders, excavators or multifunction machines. According to the invention, the generator comprises a subassembly (A) for the distribution and control of the hydraulic fluid, said subassembly (A) being provided with a piston (3) which distributes the hydraulic fluid under pressure to a hydrologistor (4) made in the 3/2 version, a high-pressure hydro-pneumatic accumulator (5), a low-pressure hydro-pneumatic accumulator (6) and several one-way valves (7 and 8), mounted in a supply circuit (P) and a discharge circuit (T), the piston (3) being in Hertzian contact with a striker (1) which has an annular surface (a) and is mounted in an intermediate subassembly (B), a support subassembly (C), and an end subassembly (D) joined together using some holding means, such as some tie members.
