Fluid filter and head with quick connector

摘要

A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.

1. A fluid filter, comprising:
a housing defining an interior space; a filter element disposed within the interior space of the housing, the filter element having a filtered fluid side and an unfiltered fluid side; a protrusion extending beyond an end of the housing in a longitudinal direction away from the interior space; the protrusion defining an inlet fluid flow passage that is in fluid communication with the unfiltered fluid side of the filter element, and an inlet to the inlet fluid flow passage; the protrusion further defining an outlet fluid flow passage that is in fluid communication with the filtered fluid side of the filter element and an outlet from the outlet fluid flow passage; a first seal and a second seal disposed on an outer surface of the protrusion and extending circumferentially around the protrusion, the first seal is spaced from the second seal in the longitudinal direction, the first seal is disposed between the inlet to the inlet fluid flow passage and the outlet from the outlet fluid flow passage, and the second seal is disposed between the outlet from the outlet fluid flow passage and the end of the housing; and a lock channel formed in the outer surface of the protrusion between the second seal and the end of the housing.
