Abstract
Abstract A dual pneumatic tire inflator is provided for simultaneously adding and equalizing the air pressure in dual tires commonly employed in tractor trailer trucks, airplanes, tractors and other dual wheeled vehicles. The dual pneumatic tire inflator includes a housing having an inlet valve for receiving pressurized air from a common air pressure source and a pair of pressure hoses connected to a pair of locking valve tire chucks for engaging each valve of the dual tire assembly and a pressure gauge for indicating the common pressure of the dual tires and a relief valve for adjusting and equalizing the air pressure in the dual tires. The housing is preferably of an elongated body having an inlet disposed at one end, a pressure gauge disposed at the other and the two pressure hoses and pressure relief valve disposed in a planar relationship.
