Problems solved by technology

Due to the corresponding adaptation of the pressure sensor to the high temperature and of course the increased manufacturing costs, this has led to the fact that electronically supported repair kits have hitherto been rarely used

Embodiment Construction

[0026] figure 1 Schematically shows the construction of a small compressor 1 in an electronically supported maintenance aid with a reciprocating piston compressor 3 driven by an electric motor 2 for the purpose of reversing the components not shown in detail here Vehicle tires are sealed and pumped. In addition, a control unit or control unit (MCU=Motor Control Unit) 4 for controlling maintenance aids or small compressors is provided here.

[0027] The control device 4 is obtained via a motor control unit / motor drive 5 (MD=Motor Drive), via a user interface 6 (UI=User Interface), ie, for example, via a control panel, an operating panel, or an application (App) on a smartphone User requirements to control air compressor / mini compressor 1 functions.

[0028] In order to operate the control device 4, an electronic "pressure measurement" is provided, which in the embodiment of the method according to the invention used here works in a non-contact inductive manner by analyzing th...

Abstract

A method for measuring the pressure generated by an electrically driven compressor, preferably a reciprocating piston compressor (3) electrically driven via a crank-and-rod drive, wherein the electric motor ( 2) the rotational speed change in relation to the pressure change at the outlet of the compressor and provide or display it as a pressure-proportional parameter for operating the compressor in the form of an input parameter to the control or regulation unit (4 ).

Description

technical field [0001] The invention relates to a method for measuring the pressure generated by an electrically driven compressor, preferably a reciprocating piston compressor electrically driven via a crank drive. Furthermore, the invention relates to a portable compact compressor with a compressor driven by an electric motor, preferably in a service aid for sealing and pumping of vehicle tires, which compact compressor has a A control device or control unit for controlling the maintenance auxiliary equipment. Background technique [0002] The compressor is for example required to carry or be part of a device for sealing and pumping inflatable objects, in particular for sealing and pumping motor vehicle tyres. These devices are called "service aids" or "service kits". [0003] These portable and lightweight units contain a compressor unit as a source of compressed air, in addition to having a sealant container for a self-sealing compound (for isolating tire damage) that ...
