Problems solved by technology

On the downside, from a construction point of view, side-channel compressors routed through electrical harnesses are relatively complex and large
Also, as the length of the cable harness increases, so does the susceptibility to EMC disturbances and / or vibrations

Embodiment Construction

[0028] figure 1 and figure 2 Both show a preferred exemplary embodiment of a side channel compressor, generally designated 1, for compressing a gas, eg for compressing air or blow-by gas of an internal combustion engine. exist figure 1 In , a perspective view of a side channel compressor 1 with a housing designated with reference numeral 2 can be seen. The housing 2 itself has an internal installation chamber into which at least one impeller drive 4 is exemplarily arranged for driving gas through a side channel 5 formed by the housing 2 .

[0029] The side channel 5 is designed for example for deflecting the flowing gas by 270° and is fluidly connected to a supply channel 8 formed in the housing 2 and to a discharge channel 13 also formed in the housing 2 . Here, the supply channel 8 is used to supply gas to the side channel 5 and the discharge channel 13 is used to discharge gas out of the side channel 5 . according to figure 1 , the supply channel 8 is divided into two...

Abstract

The invention relates to a side channel compressor for compressing a gas, which includes a housing, in which a side channel is arranged, which can be supplied with gas via a feed channel formed within the housing for feeding gas to the side channel and a discharge channel formed within the housing for discharging gas out of the side channel, wherein in the housing an impeller drive is arranged, wherein the side channel compressor includes a drive control for regulating and / or controlling the impeller drive. The impeller drive includes an impeller which on the output side engages in the side channel of the housing in order to drivingly interact with a gas. The side channel is designed for redirecting the gas flowing through the side channel by at least 270 degrees. The drive control includes an integrated pressure sensor for measuring a gas pressure of the gas flowing within the side channel.

Description

technical field [0001] The invention relates to a side channel compressor for compressing gas according to the preamble of claim 1 . Background technique [0002] DE 10 2017 221 318 A1 describes an internal combustion engine with crankcase ventilation, which comprises an electrically driven delivery which is fluidly connected to the crankcase by means of a blow-by gas line. The electrically driven conveying device can be designed as a side channel compressor comprising a rotating bladed impeller which generates a pressure difference between the inlet and the outlet of the side channel compressor, wherein the pressure at the inlet lower than the outlet pressure. The vane wheel drive can be controlled in an adjustable manner by means of a drive controller, wherein a pressure regulation is used which measures the gas pressure in the crankcase ventilation by means of a pressure sensor. The pressure sensor can be arranged in the crankcase, at the inlet of the conveying device o...
