Latest Patents

Randolph holds a patent for an air admittance vent (AAV). This invention features a cup-shaped vent body and a vertically reciprocating valve element. The valve element seats against a valve seat that has two separate contact areas defined by an annular ridge and a conical face formed in the bottom of the vent body. When the valve element moves into its closed position, the pliable diaphragm of the valve element initially contacts the annular ridge, forming a first part of the valve seat. This is followed by the diaphragm moving fully into sealing contact with the conical face, which forms the second part of the valve seat. The initial contact with the annular ridge provides a first seal before the diaphragm nests into contact with the conical face to create a second seal with the valve seat.
