Abstract

PURPOSE: To automate drain discharge by a mechanism wherein differential pressure is detected between filter inlet and outlet, whose result is employed to cause the liquid pressure of either filter inlet or outlet to open the main valve to discharge drain outside.
CONSTITUTION: When drain concentration in filter chamber increases, self-cleaning function decreases, and the pressure loss at filter outlet and inlet increases and the pressure difference between them causes the auxiliary valve member 11 to be released from the valve seat 8. Part of oil at the filter inlet side passes through oil chamber 4 and enters the oil chamber 15. The main valve member 18 is released from the main valve seat 16. High concentration drain in the filter chamber is discharged through drain chamber 12 to drain tank. This recovers self-cleaning function, the auxiliary valve member 11 closes, oil in the oil chamber 15 is returned through orifice 19 to the oil tank, the main valve member 18 closes, and drain discharge to the outside of the system is stopped.
