ABSTRACT:
An acoustic alarm arrangement associatable with a pneumatic tire for generating a signal indicating that pressure of gas in the tire decreases from a predetermined magnitude, has a housing arranged to be connected with a tire and bounding an inner chamber, a signal element associated with the housing and actuated under the action of a strike, and a striking element movable in the inner chamber between an inoperative position in which it is spaced from the signal element and an operative position in which it approaches and strikes the latter. The striking element subdivides the inner chamber into a first compartment communicating with the interior of the tire, and a second compartment. A valve is located in an inner passage of the striking element and movable to a closed position in which it closes the inner passage of the striking element and disconnects the compartments from one another whereby gas at a predetermined pressure from the interior of the tire is admitted into the second compartment and counteracts the force of a spring and retains the striking element in the inoperative position and to an open position in which the inner passage is open and gas under decreased pressure flows from the interior of the tire into the second compartment, and opened further into the first compartment whereby gas pressures in the compartments become substantially equalized and the spring moves the striking element to the operative position.
