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...
