FIELD: hydraulics. SUBSTANCE: mechanism comprises housing with gas power accumulator and cocking chamber. There are a striker with a head and a step valve spring-loaded by flexible power accumulator inside the chamber. The outer side of the valve and inner side of the housing define a chamber that is periodically connected with the cocking chamber. Grooves are provided on the inner side of the housing at the top of the space. The grooves and the step valve form a labyrinth slot. The step valve can interact with the housing and overlap the labyrinth as well as defines the delivery space. The inner side of the step valve and head of the striker define the under-valve space which is in communication with the delivery space through passageways in the valve when the striker is cocked. The space is constantly connected with the drain pipe line. The cocking chamber is constantly in communication with the delivery pipe line. EFFECT: improved design. 1 dwg |
