Abstract
A venting apparatus comprising a housing having a chamber, an inlet through which fluid can be supplied to the chamber, a liquid outlet through which liquid can leave the chamber and a gas vent through which gas can leave the chamber. The apparatus also includes a pivot arm and a valve element for opening and closing the gas vent to control the flow of gas through the gas vent. The valve element is carried by the pivot arm. A pivot device mounts the pivot arm for compound movement relative to the housing to move the valve element to open the gas vent. A first portion of the compound movement is about a first fulcrum and a second portion of a compound movement is bodily away from the gas vent and is different from the first portion of the compound movement. A float is mounted for movement in the chamber and is drivingly coupled to the pivot arm to drive the pivot arm to bring about such compound movement.
