Abstract:
1. A support of a proximity sensor of a compressor's piston, the compressor comprising: a cylinder for the piston; the cylinder including a valve plate placed at an end of the cylinder to define a border between a high-pressure region inside the cylinder and a low-pressure region outside the cylinder; the valve plate defining a bore extending from the high-pressure region to the low-pressure region; the support comprising: a substantially oblong, planar, and rigid base structure, the base structure extending from a first connection end portion of the base structure to a second connection end portion of the base structure along a surface of the valve plate, the base structure forming a single piece integral with the first connection end portion and the second connection end portion, the first connection end portion and the second connection end portion being in electrical communication with each other through one or more electric interconnections; the proximity sensor fixed to the first connection end portion of the base structure and configured to extend at least partially through the bore in the valve plate such that at least a first portion of the proximity sensor is positioned inside the high-pressure region of the cylinder in order to detect the piston and at least a second portion of the proximity sensor is accessible from the low-pressure region; the first connection end portion configured to support the proximity sensor from the low-pressure region and to electrically interconnect the proximity sensor to the second connection end portion, the second connection end portion extends, at least partly, beyond the border of the valve plate.
