Abstract

Inventia se refera la un generator de soc, hidraulic, utilizat ca echipament pe excavatoarele hidraulice sau ca instalatii autonome pentru baterea pilotilor, sfarâmarea supragabaritelor în minerit, dezbaterea oalelor, de zgura etc. si constituie o perfectionare a inventiei principale cu brevetul nr. 90700. Generatorul de soc, conform inventiei, este prevazut cu o supapa de sens încorporata în distribuitorul inertial, în vederea asigurarii legaturii hidraulice a camerelor, inferioara si superioara, la cursa de coborâre a distribuitorului inertial si de întrerupere a acestei legaturi la cursa de ridicare a pistonului.The invention relates to a hydraulic shock generator, used as equipment on hydraulic excavators or as autonomous installations for piloting, breaking of overburden in mining, potato debate, slag etc. and constitutes a refinement of the main invention with the patent no. 90700. The shock generator according to the invention is provided with a sense valve incorporated in the inertial distributor in order to ensure the hydraulic connection of the lower and upper chambers to the lowering of the inertial distributor and the interruption of this connection to the lifting stroke of the piston.
