Mono-block control valve with regeneration conduit |
摘要 |
<p>A mono-block control valve having a regeneration conduit is disclosed. The regeneration conduit does not enlarge the valve body. The control valve has a bypass conduit formed in either side of the valve body. The bypass conduit is opened to return the pressurized oil of the hydraulic pump to a return tank if the spool is in a neutral position, but closed if the spool moves. Two actuator ports are formed in each section of the body. The ports supply the pressurized oil of the pump to a supply side of each actuator and for returning the oil coming out of the return side of each actuator to the return tank respectively. A regeneration conduit is formed in a bottom portion of the body and connects the two actuator ports to each other. The control valve further includes a check valve and a pilot conduit. <IMAGE></p> |
