Abstract:
The compression device according to the invention includes first and second compressors mounted in parallel and an oil level equalization line arranged to fluidly connect the oil sumps of the first and second compressors. The oil level equalization line includes at least one oil level regulating portion positioned near one of the first and second compressors and including a dam wall extending transversely to the longitudinal direction of said oil level regulating portion and a flow opening arranged such that, when the oil level in the oil sump of the compressor situated near the oil level regulating portion extends above the upper level of the dam wall, oil flows through the flow opening toward the other compressor.
