Beschreibung
Zusammenfassung:	A compressor or pump assembly including a housing, a compression mechanism disposed within the housing, a shaft operatively connecting the compression mechanism and a drive source, the shaft having an axis of rotation and first and second surfaces, the shaft axis of rotation disposed between the first and second shaft surfaces, and a counterweight disposed about the shaft and comprising first and second portions, the first counterweight portion generally U-shaped, having first and second arms, the first arm in contact with the first shaft surface, the second arm in contact with the second shaft surface, the second counterweight portion extending between the first and second arms and attached to the first counterweight portion, the shaft captured between the first and second counterweight portions, whereby rotation is imparted to the counterweight through the interface of the shaft surfaces and the arms.
