REFRIGERANT COMPRESSOR UNIT Russian patent published in 2024 - IPC F04B37/18 F04B39/02 

FIELD: refrigerating or freezing equipment.

SUBSTANCE: invention relates to refrigerant compressor unit. Refrigerant compressor unit, including piston compressor (40) driven by drive motor (50), as well as common housing (12), having housing part (16), which forms 5 housing section (32) of drive with drive compartment (34) for piston compressor (40) and forms housing section (42) of engine with engine compartment (44) to accommodate drive motor (50), wherein the cooling agent supplied to piston compressor (40) flows through engine compartment (44) so that in the bottom part of engine compartment (44) lubricant tray (162) is formed, from which the lubricant is pumped out by means of pumping device (150) and transferred to lubricating bath (132) in drive compartment (34). In the bottom part of engine compartment (44) there is intake point (164), which is made in such a way that it is primarily at inclined positions of the refrigerant compressor unit (10) relative to the initial position, which are in the range of permissible inclinations, takes the lubricant from lubricating pan (162) and supplies it to pumping device (150).

EFFECT: invention shall ensure reliable pumping out of lubricant from the lubricating tray when the compressor unit of the refrigerant is inclined relative to the horizontal longitudinal direction.
