A squeeze film damper assembly for a compressor includes a damper sleeve configured to be disposed about a rotor shaft of the compressor. The damper sleeve includes a pressure dam pocket formed in an inner circumference of the damper sleeve. The pressure dam pocket is configured to receive a flow of lubricant and to pressurize the flow of lubricant via rotation of the rotor shaft. The damper sleeve includes an outlet passage extending from the pressure dam pocket to an outer circumference of the damper sleeve. The squeeze film damper assembly also includes a bearing housing disposed about the damper sleeve to form a damper gap extending between the outer circumference of the damper sleeve and the bearing housing. The damper gap is fluidly coupled to the outlet passage and is configured to receive the flow of lubricant from the pressure dam pocket.
