<p>The spring-loaded intermediate valve is formed as a seat valve. It has a control spring in positive connection with a spring plate, which merges into a piston, integral with the valve seal. The piston (5) of the spring plate (4) and the section (6) of the valve housing (1) surrounding it, afe sealed by a close fit. The valve seal member (7) has an associated valve seat (8) on the housing section. The active cross section of the piston is chosen, so that the force applied by it due to the opening pressure of the hydraulic fluid is larger than the increase in force of the control spring (3) during opening.</p> |
