ABSTRACT:
An automotive bicycle tire pump is disclosed in which a cylinder and piston assembly rotates with the wheel rim and tire. The piston is reciprocated by contact with a stationary cam to provide pressurized air to the tire. When the proper tire pressure is reached, the piston is automatically latched in a position out of contact with the cam to prevent reciprocation of the piston.
