PURPOSE: To realize a connection of a pump to ducts in a housing of a work apparatus in a simple and time-saving manner with this connection being seal- tight as to a medium under pressure.
CONSTITUTION: A suction connection 8 and a delivery connection 9 have terminals in annular slots 19, 20 formed between at least three sealing rings 15, 16 and 17, 18 which are made of an elastomeric material and are injection molded on an outer jacket 14 of a stator 1. Thus, since both the suction connection and the delivery connections pass in the annular slots formed between the at least three sealing rings, ducts for liquids provided in a housing can be disposed in any rotational position relative to the stator. This affords an advantage that connection of a pump into the housing of a work apparatus can be made in a labor- and time-saving manner.
