FLUID FILTER DRAIN ASSEMBLY

摘要

A drain assembly for a diesel engine fuel filter has separate drain (40) and vent (41) valves mounted closely adjacent one another in the bottom wall (28) of a collection bowl of a filter and intercoupled so that actuation of the drain valve (40) also actuates the vent valve (41) after the drain valve (40) has been opened. The vent valve (41) is a spring biased valve located higher than the drain valve and preferably is a tyre core type valve. The drain valve (40) may be a spring biased push type valve or a valve threadedly mounted in the bottom wall (28) of the collection bowl for vertical movement to open a valve seat (49) in the collection bowl and in either embodiment includes a shoulder (50) interengageable with a pin (65) of the vent valve (41) for actuation of the vent valve. The drain valve includes a hose connector (52) which rotates relative to the collection bowl or cartridge assembly to facilitate replacement of the cartridge assembly, the threaded type drain valve including a snap-in type swivel for the hose connector.
