Abstract
A valve-in-head filter includes an outer housing (2) adapted to receive a fluid filter cartridge (4) therein. A valve head (7) is provided which includes an annular stand pipe (22) for locating an end of the filter. The stand pipe is cut away (32) on its downstream side to reduce fluid back pressure. Furthermore, a passage (13) is disposed between the head inlet (11) and outlet (12), with the passage receiving a slidable plunger (23) therein. A manually actuatable handle (28) connects through a rotary actuator (29) to move the plunger. The actuator includes a stem (30) mounted eccentrically to the handle axis, with the stem received in a recess (31) in the plunger so that turning of the handle moves the plunger between 'on' and 'off' positions. The plunger includes a seal (26) which continuously engages the passage wall in all plunger positions, and the construction provides full 'on' and 'off', with no fluid bypass in the 'off' position.
