Abstract
A tire pressure gauge is provided. The tire pressure gauge is mounted on a rim of a wheel or on a hub of the wheel. An interconnection is made to the valve stem of the wheel. The interconnection includes a tap that directs pressure from the interconnection via a tube or conduit to the gauge. The interconnection can provide continuous pressure to the gauge or can be actuated by the movement of an operator at a predetermined inspection time. The gauge can be mechanical or electronic.
Claims17
A tire pressure monitoring apparatus, comprising:
- a gauge that displays a pressure reading;
- and
- a saddle valve including:
- (i) a base member adapted to sealingly and threadingly connect to a tire valve stem,
- (ii) an upper member constructed and arranged to move relative to the base member at a predetermined time to provide fluid communication between a tire and the gauge, and
- (iii) a locking mechanism that, when engaged, secures the upper member in a position that maintains the fluid communication between the tire and the gauge until the locking mechanism is disengaged.
