Definitions
- the present invention relates to a compact inflating unit with sealing facilities for a tyre filled with air including a source of compressed air, for example an electrically driven compressed air compressor, where a duct for compressed air connects the source of compressed air with a filling connector, which can engage the filling valve of the tyre, as a selector device is inserted between the source of compressed air and the filling connector, where the selector device either can lead the compressed air directly from the source of compressed air to the filling connector or can leads the com- pressed air through a container with a sealing agent to the filling connector.
- a source of compressed air for example an electrically driven compressed air compressor
- a duct for compressed air connects the source of compressed air with a filling connector, which can engage the filling valve of the tyre, as a selector device is inserted between the source of compressed air and the filling connector, where the selector device either can lead the compressed air directly from the source of compressed air to the filling connector or can leads the com-
- Such an apparatus is described in US 4 765 367 and can be used to both refilling air into a car tyre and to mend a tyre puncture.
- the apparatus is a compact type that can either be carried as an accessory in a car, or mounted in the car without occupying much space.
- the container with sealing material is provided separately and is connected to a selector device, which consists of a valve arrangement.
- the valve has two positions, one of which compressed air is led to and though the container in order to conduct sealing material to the filling connector and thereby to the tyre, and another position where compressed air is led directly to the filling connector.
- the insert When the the unit is usen for inflating, the insert is placed in the selector device, and inflating may be effected. When mending a puncture is needed, the insert is substuted with the container containing sealing agent, and mending may be performed. When not in use, the container can be stored somewhere and apart from the inflating unit, so that it is not needed to carried with the unit.
- the container is provided with a neck, which can engage a socket in the inflating unit, for example by a screw connection, and where the socket comprises a perforation member for breaking a sealing in the neck of the container, where the perforation member consists of a sharp edged pipe connector provided as a part of the duct of compressed air and protruding into the socket, and where the insert has a recess or cavity for accommodating the pipe connector and simultaneously allowing air to pass from the pipe connector to a downstream section of the air duct.
- the container is just mounted in the socket, whereby the sealing is broken, and by introducing compressed air, the sealing material is forced out of the container.
- a check valve is provided for preventing flow from the pipe connector and in the direction of the source of compressed air.
- Fig. 1 shows a front view of an inflating unit according to the invention
- Fig. 2 shows an inflating unit according to Fig. 1, but where the upper cover is removed
- Fig. 3 shows a section on the line III-III in Fig. 1 in a first embodiment of the inflating unit according to the invention
- Fig. 4 shows the same section as Fig. 3, but of a second embodiment of the inflating unit according to the invention, and where a bottle with sealing material is mounted instead of a plug in the unit
- the inflating unit can be arranged in a rectangular and relatively flat box or cabinet 1, which on its front is provided with an electronic switch 2 and a manometer 3 which all the time detects the excess pressure in the duct of compressed air of the apparatus and the connected parts.
- a container with sealing material which can be a latex suspension or an other known sealing agent.
- the container 4 is provided in the shape of a bottle made of synthetic materials. Of course other geometries and materials can be used for the container 4.
- the unit as shown on Fig. 2, comprises an electric motor 5 with an output shaft 6, which by a crankshaft 7 operates a compressor piston 8.
- the motor 5 is a DC motor for 12 volt which with- out further ado can be connected to a plug for a cigarette lighter in a car, for example with a plug 9 on Fig. 2 connected with a not shown wire.
- the compressed air compressor is constructed in a known manner, as the inlet valve is built into the piston 8 and the outlet valve in outlet 10 from the compressor.
- Thus out- let 10 forms the first section of the duct of compressed air, which extends from outlet 10 and forward to a tube 12 which, in a not shown way, is provided with a connector for connection to a valve on a tyre.
- the apparatus is provided with a safety valve 13 and an air-escape valve 14
- the compressed air duct is formed as an elbow pipe, which ends in a sleeve 15.
- a intermediate piece 16, 16' constituting the essential part of the invention.
- the intermediate piece 16 is attached to the unit with two screws 17, see Fig. 2.
- the intermediate piece 16, 16' is provided with a connection 18 for the container 4 in the form of a screw socket 18.
- a pipe connector 19 protrudes, provided with a slanting cut 20 and a sharp upper edge 24.
- the pipe con- nector 19 is part of the duct of compressed air and communicates with the outlet 10.
- the duct of compressed air continues at the bottom of the socket 18, here shown by the number 21.
- an insert or plug 22 is inserted into the socket 18.
- the plug 22 has an airtight abutment against the bottom of the socket 18 by means of a sealing ring 23. It can be seen on Fig. 3 that the plug in that way completely closes the admission of compressed air to the environment.
- the compressed air which flows from the duct, passes into a cavity 25 in the plug 22, from where the air passes between the inner walls of the cavity 25 and the outer walls of the connector pipe 19 down to the continuation of the compressed air duct 21.
- the plug 22 When the unit is used for mending a tyre, the plug 22 is unscrewed, and a bottle 4 with sealing material is screwed on, as the sharp upper edge 24 of connector 19 cuts though the film sealing which initially covers the opening of the bottle 4. In the same way as the plug 22, the opening of the bottle 4 is sealed with a sealing ring 23 in relation to the bottom of the socket 18.
- compressed air By activating the compressor, compressed air is lead into the bottle 4 and the sealing material is pressed out through the duct piece 21 and out into the tube 12.
- the unit as shown on Fig. 4 with a intermediate piece 16' where a check valve 27 is disposed between the pipe connector 19 and the up-stream sections of the duct of compressed air.
- the check valve consists of a ball 28, which in a closed position can fit into a small hole 29, while in an open position it is pressed up against a mesh 30, where air can pass around the ball 28 and into the pipe connector 19.
