Abstract: The present invention relates to a compression chamber unit (1) of an air pump, comprising a cylindrical body part (3) provided with at least one outlet nozzle (4), a number of connecting flanges (6) and a number of connecting bosses (7), wherein the cylindrical body part (3) is an extruded cylinder and a cap (2) is formed with outlet nozzle (4), connecting flanges (6) and connecting bosses (7), where the cap (2) is adapted to engage with a first end part (10) of the cylindrical body part (3). The present invention further more relates to a method for forming a compression chamber unit (1) which method comprises the following steps: the cylindrical body part (3) is extruded, and the cap (2) is moulded onto the cylindrical body part (3).

Abstract: A pump unit for use in pumping and repairing car tyres has a box-like jacket (1) in which is provided a socket (10) for fixing a bottle (8) with repair fluid and with a lid/adapter (4) known per se with a large and a small collar (5, 6). By the invention is provided securing of the adapter (4) and thereby of the bottle (8) by providing the socket with two resilient arms (16) that may grip with projections (17) around the large collar (5) behind existing edges (7), thus forming a spring catch for the adapter (4). Hence is provided secure holding of the adapter (4) and ready insertion and removal of the bottle (8) in a simple way.

Abstract: A device for inflating a tire having gone flat to a wanted pressure and for sealing and inflating a puncture tire. The device includes a compressed-air source, a tubular container filled with a sealing agent, and a first conduit having an adapter at its second end for connecting the conduit to a valve on the tire. The container furthermore has an inlet opening for passage of compressed air from the compressed-air source and an outlet opening for passage of sealing agent. The container is enclosed by a tubular cylinder having at one end an aperture closed by a cover. The cover is mounted displaceable on the cylinder between a first operative position and a second operative position. Thereby, it is obtained that the device is quick and easy to operate. Sealing and inflating of a puncture tire are done in between one and three minutes. Packed up, the device takes up practically no space whereby the heavy and bulky spare wheel is made unnecessary.

Abstract: A compact combination apparatus for inflating and mending a car tyre comprises a compressor with an outlet (10), where compressed air is lead to a tube (12) for connection to the filling valve of the tyre. In the duct of compressed air, an elbow pipe connector is provided (19), which can break the sealing on a bottle (4) with a sealing material and lead compressed air into the bottle, and by that pressing the sealing material out into the tube (12) through a pipe opening (21) at the end of the opening of the bottle. When the inflating unit is used only for refilling a tyre with air without mending it, a plug is inserted (22) in the socket (18) where the bottle (4) is to be fitted that, thus preventing admission of compressed air to the environmental and instead conducting compressed air to the tube (12) through a clearance between a cavity (25) in the plug (22) and the pipe connector (19).
