A filter assembly has a head portion (12) comprising a housing (20) having inlet means (16) and outlet means (18) for inlet and outlet of fluid respectively and a filter (14) releasably connectable to the head portion and being adapted to receive a flow of fluid from the inlet means and return it to the outlet means. The assembly has valve means (28) within the housing displaceable between a first, closed position, and a second, open position. The filter portion (14) is engageable with the valve means (28), in which condition the filter portion is displaceable with respect to the housing (20) of the head portion between a first position in which the filter portion (14) is disconnected from the head portion and disengageable from the valve means (28) and a second position in which the filter portion (14) is connected to the head portion (12). Displacement of the filter portion (14) between the first and second portions causes the valve means (28) to be displaced between its closed and open positions. |
