Venting apparatus

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;
• a valve element for opening and closing the gas vent to control the flow of gas through the gas vent;
• a pivot arm, said valve element being carried by the pivot arm;
• fulcrum surfaces carried by the housing and the pivot arm which are engageable to provide a first pivot axis for the pivot arm;
• a member carried by said housing;
• said member and said pivot arm having cooperating portions for mounting the pivot arm for pivotal movement about a second pivot axis and which allows movement of the pivot arm to permit the fulcrum surfaces to engage and disengage;
• and
• a float mounted for movement in said chamber and drivingly coupled to said pivot arm to drive the pivot arm.

A venting apparatus comprising:

• a valve for opening and closing the gas vent to control the flow of gas through the gas vent, said valve including a valve seat adjacent the gas vent and a valve element engageable with the valve seat to close the gas vent and movable away from the valve seat to open the gas vent;
• a pivot arm, said valve element being carried by the pivot arm;
• a pivot device for mounting the pivot arm for compound movement relative to the valve seat to move the valve element away from the valve seat to open the gas vent, a first portion of said compound movement being about a first fulcrum and a second portion of said compound movement being bodily away from the valve seat and being different from the first portion of said compound movement;
• and
• a float mounted for movement in said chamber and drivingly coupled to said pivot arm to drive the pivot arm to bring about said compound movement.
