Abstract
Systems and compression assemblies thereof are provided. In one example aspect, a system includes a cooling fluid circuit and a piston slidably received within a chamber of a casing. The casing defines an inlet passage and an outlet passage. The inlet passage receives a cooling fluid, e.g. oil or a refrigerant, from the cooling fluid circuit. The cooling fluid flows into the inlet passage and downstream into an inlet groove defined by the piston along its outer surface. The cooling fluid flows downstream to a cooling channel defined by a piston head of the piston and thereafter into an outlet groove defined by piston along its outer surface. The cooling fluid then flows into outlet passage of casing and is returned to cooling fluid circuit. The passage of cooling fluid through the passages, grooves, and channels removes heat from the casing and the piston.
