[88] 2/2-way valve (1)
The 2/2-way valve has a
working port A, a supply port P and a leakage-oil port L. In the
case of the valve shown here, of slide design, flow from P to A
is closed in the normal position.
A relief line leading to the leakage-oil port is provided to prevent a build-up of pressure in the spring and piston chambers.
