ORDER A HYDRAULIC MOTOR WHIT PRESSURE DAMPING PEAKS

THEME  A reversible  hydraulic motor control using constant flow pump will provvidc cushioning  devices rest on both sides
OPERATION   Entry pathways depending on the fluid in the hydraulic motor dealer will turn right or left or to rotat. The scheme heaving to distributor 4/3 with common center all flow pump will be switched to tank.Determine flow pump hydraulic motor rotation speed .Operator by electrical contacton the distributor plunger arrows move parallel engine spinninig in one direction and when the change has crossed arrows reverse.
 Interesting is that the system has high pressure suplly and discharge is in depression in this case the effect of
cavitation is drinking so engine protection is achieved  by limiting the pressure that take the pressure peaks
  In this case are two limiting pressure mounted in parallel with the engine mounted hydraulic pressure P1 to the limiters are set to valve greater than P pressure relief valve set to pump( P1>P  )Depreciation during the oil

circulating  in closed circuit.To stop the hydraulic motor moment of inertia due to the hydraulic motor for a short time wll run the pump until the final stop.Displaced fluid passes through the hydraulic motor refuled pressure
limiter Damping devices can pose a cavitatin if the hydraulic motor has not been verified by cavitation effect when projected
