AI Technical Summary

Technical Problem

Existing compressor devices for cooling systems, such as those used in magnetic resonance imaging apparatuses and quantum computers, suffer from significant power losses due to motor-driven rotary valves and require large installation spaces due to complex mechanical connections.

Method used

A compressor device featuring a cylinder with a transfer space filled with a transfer fluid, a piston for periodic motion, and a metal bellows compressor element, where the operating gas is indirectly compressed by the displacement of the piston through the transfer fluid, eliminating the need for a rotary valve and simplifying the mechanical configuration.

Benefits of technology

This configuration reduces power losses, improves efficiency, and allows for a more compact design by eliminating the rotary valve and simplifying the mechanical layout, while also preventing contamination and extending the service life of the compressor element.

Abstract

The present invention relates to a compressor device (2), which comprises a cylinder (4), a transmission space (16) located in the cylinder (4) and filled with a transmission fluid, defining a piston (6) that can be periodically reciprocated by a drive device (26), a compressor element (8) disposed in the transmission space (16) and defining an operating space / compression space (20) filled with an operating gas, in particular a (metal) bellows, and a connector (10) capable of connecting the operating space (20) and an operating gas pipeline (36) to a Gifford-McMahon cooler or a pulse tube cooler (38), wherein the compressor element (8) and the operating gas contained therein are indirectly and periodically compressed by the transmission fluid displaced by the piston (6).
