A needle bearing for use in a pump has an inner race, embodied as an eccentric sleeve, needles, and an outer race with rims oriented radially inward on both of its face ends, of which one rim is intended to secure the axial position of the needles and the outer race by engagement with the inner race, in that a rim fits over one end face of the inner race. In the pump unit, the needle bearing is disposed with an axial gap from a roller bearing on a shaft of a drive motor. The rim of the outer race engages this gap.

A sound absorber for a blower has a housing having an air inlet opening, an axially arranged air outlet passage, and a substantially spiral-shaped passage which connects the air inlet opening with the air outlet passage, a sound absorption material which forms walls of the substantially spiral-shaped passage, and reflector which at least partially surrounds the air outlet passage and screens the air outlet passage in direction of an air inlet opening.
