Embodiment Construction

[0020] The only figure shows a compressor unit 1 in a portable source of compressed air, the compressor unit having a reciprocating piston compressor 3 driven by an electric motor 2, wherein the reciprocating piston compressor comprises The mass crank gear 4 vibratingly moves a piston 6 in a cylinder 5 such that the cylinder 5 and the piston 6 define a compression chamber. The cylinder 5 is closed on the output side by a cylinder head 7 with an outlet valve 8 . The compressor unit has an electromechanical pressure switch 9 connected to the pressure in the compression chamber, and the electromechanical pressure switch is connected to a certain pressure value in the compression chamber (i.e. at a predetermined maximum value) through an electrical wire 10. In the case of P0), the motor 2 is switched off, and the motor 2 is switched on again when the pressure drops below the pressure value.

[0021] In the event of a drive motor shutdown, the pressure in the compressor cannot con...

Abstract

The invention concerns a compressor unit in a portable compressed air source comprising a piston compressor driven by an electric motor, the piston compressor comprising a piston which is moved in oscillating manner in a cylinder via a slider crank mechanism and the cylinder being closed on the output side by a cylinder head with an outlet valve, the compressor unit comprising an electric pressure switch which is connected to the pressure in the compression chamber and it being possible for the electric motor to be switched on and off via the pressure switch.

Description

technical field [0001] The present invention relates to a compressor unit in a portable source of compressed air, the compressor unit having a reciprocating piston compressor driven by an electric motor, wherein the reciprocating piston compressor comprises a slider crank transmission ( Schubkurbelgetriebe) vibratingly moves a piston in a cylinder such that cylinder and piston define a compression chamber, wherein the cylinder is closed on the output side by a cylinder head with an outlet valve. Background technique [0002] Such compressor units are for example required with or as part of means for sealing and pumping inflatable objects, especially for sealing and pumping motor vehicle tires (repair kits). [0003] These portable and lightweight units contain a compressor unit as a source of compressed air, in addition, a sealant container for automatic sealant that can be filled into inflatable objects, a container for sealant and compressed air A valve unit and a dispens...
