HYDRAULIC DRIVE OF PISTON-TYPE CONCRETE PUMP

摘要

SUMMARY OF THE INVENTION: The control system hydroapparatuses reverse betonoras- prodelitel communicated with the control outputs of the working cylinders (GC) betonotransportnyh drive cylinders and the control cavities Hydrodistributor control HZ switching Concrete distributor. HZ switching betonoraspredelitel configured to output a control communicating with the cavity controlling the additional control decoupler, control output to- cavity communicates with the control drive controlling operation Hydrodistributor HZ. One HZ formed with two switching the gate outputs which are communicated through the valve and to the control cavity further decoupler. 2 ZP f-ly. 3 yl.
