초록

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...
