Abstract
A hose pump comprises a housing in which a drive shaft is mounted. The shaft is provided with an obliquely extending shaft piece on which a swash plate is mounted. The swash plate end face presses against a hose which lies in an annular groove located in the underside of the housing cover. The swash plate does not substantially rotate relative to the housing or to the hose and therefore exerts substantially no shear on the hose.
