In a housing, there is formed, in series, a first end cavity, a first cylinder cavity, a pressure cavity, a second cylinder cavity and a second end cavity. The cavities are separated by walls which include orifices. Two identical valve members are located in the housing. The first valve member has a piston and a valve plug in the first end cavity and a valve plug in the pressure cavity. The second valve member has a piston and a valve plug in the second end cavity and a valve plug in the pressure cavity. Pressure in the pressure cavity acts on the confro...
A switching valve for switching hydraulic pressure and return between first and second cylinder passageways, said valve comprising: a first end cavity having a first end wall; a first cylinder cavity; a first divider wall between said first end cavity and said first cylinder cavity, said first divider wall including a first valve orifice; a pressure cavity; a second divider wall between said first cylinder cavity and said pressure cavity, said second divider wall including a second valve orifice; a second cylinder cavity including a sidewall; a third div...
