Abstract

An apparatus for reinflating an object such as a punctured automobile tire. The apparatus including a valve assembly having a housing with two inputs which are connected to an outlet through passageways within the housing. A valve is provided such that the input passageway which receives the output from a compressed air source is connected, in its normal position, to the outlet of the housing for connection to an automobile tire or inflatable object. The second input to the valve assembly is opened by placing the valve in the second position. The second position of the valve closes the first input from the compressor to the outlet and seals the first input from the second input. The second input includes a threaded fitting on an aerosol type can which seals the input to the housing as well as it seals with respect to the can to which it is attached.

Claims

1. Apparatus comprising:

means for receiving a supply of pressurized gas;

means for receiving an aerosol type can containing a sealant, said sealant-receiving means comprising an internally threaded bore for receiving a correspondingly threaded fitting of an aerosol type can;

outlet means adapted for connection to an inflatable object;

valve means having a first position connecting the pressurized gas-receiving means to the outlet means, and a second position connecting the sealant-receiving means with the outlet means and closing the connection from the pressureized gas-receiving means to the outlet means;

means to prevent connection from the sealant-receiving means to the gas receiving means when the valve is in the second position; and

an aerosol-type can having a threaded fitting engaging said threaded bore, said threaded fitting having positioned adjacent thereto a valve portion activatable by the valve means when the valve means is in the second position.

2. An apparatus as claimed in claim 1 wherein the threaded fitting is adapted to prevent exhaustion of sealant or compressed gas through the connection with the aerosol type can.
