Abstract
The scroll refrigeration compressor includes a stationary volute and a moving volute provided with spiral wraps defining variable-volume compression chambers, a separating member sealably mounted on a plate of the stationary volute so as to allow a relative movement between the separating member and the stationary volute, a delivery chamber at least partially defined by the separating member and the sealed casing. The compressor further includes a bypass passage arranged to communicate the delivery chamber with an intermediate compression chamber, and a anti-return device comprising a closing member movable between closing and opening positions for closing and opening the bypass passage, and an enclosure, positioned between the separating member and the plate of the stationary volute, including a first portion sealably mounted in a housing defined by the separating member and oriented substantially parallel to the longitudinal axis of the compressor.
