A compressor having a high pressure slide valve assembly is disclosed. The slide valve assembly includes: a volume slide valve mechanism, the mechanism slidably movable to control compressor volume ratio and power input to the compressor. The assembly also includes a capacity slide valve mechanism that is in operational association with the volume slide valve mechanism, the capacity slide valve mechanism slidably movable to control compressor capacity. At least one of the volume slide valve mechanism and the capacity slide valve mechanism includes at least one groove or channel, and the at least one groove or channel provides for lubrication to ensure relative movement between the slide mechanisms in a high pressure environment. A method of controlling compressor volume ratio, power input and capacity in a compressor operating in a high pressure environment is also disclosed.
