Abstract
A refrigerant compressor that includes a compressor housing enclosing an outlet chamber and an outlet passage leading from the outlet chamber to an external high pressure connection, such that the pulsations in it are damped as much as possible. The refrigerant compressor includes a pulsation damping element inserted into the outlet passage of the compressor housing following the outlet chamber. The pulsation damping element has an inlet baffle which faces the outlet chamber and extends over a cross section of the outlet passage and, located opposite to the inlet baffle is an outlet baffle which extends over the cross section of the outlet passage. At least one reflection chamber is provided between the inlet baffle and the outlet baffle. The inlet baffle and the outlet baffle each have at least one passage which faces a reflection surface on the respectively other baffle.
