Abstract
A seal assembly for use with a float valve whereby an inlet for liquid being admitted to a reservoir is shut to cut off liquid flow when a predetermined level of liquid has been admitted to the reservoir. The seal assembly comprises an adjustment knob and a collar located around the knob. The knob is used to select the level of liquid in the reservoir at which sealing is required and has a portion which is eccentric with respect to an axis of rotation of the knob. The collar has an inner wall which bears against the eccentric portion so that it can move radially upon rotation of the knob and make sealing contact with an inlet nozzle. An obstruction region provided on the collar, at which sealing occurs, has a deflector to either side so that spray from the inlet nozzle is controlled. Structure is provided to limit rotation of the collar with the knob. Conveniently, the arrangement provides adequate sealing with controlled spray characteristics relatively independently of the position of the adjustment knob.
