摘要： A filter apparatus (10) comprises a housing (18), a filter element (14), and an anti-drainback valve (24). The anti-drainback valve (24) comprises a support member (92) and a valve member (30) coupled to the support member (92) for movement between a normally closed position blocking a flow of fluid out of the housing through an inlet formed in the housing and an opened position allowing a flow of fluid through the inlet into the housing.

摘要： A fluid filter apparatus 10 includes a filter element 12 located in a filter chamber 14 formed in a filter housing 16. A valve unit 18 is located in a passageway 32, 34, 36 formed in the filter housing 16 to control flow of fluid into or out of the filter chamber 14. the valve unit 18 comprises a valve 78, a spring 80 for biasing the valve and a container 22. The container 22 has an exterior wall 66 which mates with an interior wall of the passageway 32, 34, 36 to retain the valve unit 18 in the passageway. The container defines an interior region 23 containing the valve 78 and spring 80, an inlet 74 and an outlet 76.
