Abstract
The invention relates to a device () for damping pressure pulsations for a compressor of a gaseous fluid, in particular of a refrigerant. The device comprises a housing (), a piston element () as well as a spring element (). The housing () is developed encompassing a chamber (), with an inlet opening () and an outlet opening (). The piston element (), supported such that it is stayed across the spring element () on the housing (), is disposed within the chamber () dividing the chamber () into a first chamber volume () and a second chamber volume (), as well as being disposed movably in a direction of motion () between a first end position and a second end position. The motion of the piston element () effects a change of the chamber volumes () and of a flow cross section of the outlet opening (). The piston element () is developed as a hollow cylinder with two, at least partially closed, end faces (). The piston element () herein comprises at least one through-opening () developed as a fluidic connection between a chamber volume () and a volume encompassed by a wall of the piston element ().
