A skateboard truck and hanger therefor, the skateboard truck including a base plate, a bushing support, and a hanger which is dimensioned for removable securement to the bushing support. The hanger is preferably removably secured to the bushing support by means of machine screws passing through openings in the bushing support for threaded engagement in threaded openings within the hanger.

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.

A compressor having a dual slide valve assembly is disclosed. The slide valve assembly includes: i) a volume slide valve mechanism that is slidably movable to control compressor volume ratio and power input to the compressor; and ii) a capacity and volume slide valve mechanism that is in operational association with the volume slide valve mechanism, and the capacity and volume slide valve mechanism is slidably movable to control compressor capacity and to control volume ratio and power input to the compressor. In at least some embodiments, the compressor is a rotary gas compressor for a compression (e.g., refrigeration) system. A method of increasing compressor efficiency using the dual slide valve assembly is also disclosed. Compressor volume load and/or volume ratio and/or compressor power input can be simultaneously controlled by both the volume slide mechanism and the capacity and volume slide mechanism. Advantageously, compressor efficiency is increased.
