Abstract (en)
[origin: WO03078841A1] The invention relates to a pump (1) with an oscillating part, wherein said pump has a housing (2) with a working chamber (3) and a crankcase (4) defined by said chamber by means of the pump part. A pump drive mechanism (6) with a drive shaft (7) is located inside said crankcase and the drive shaft is mounted on bearing (8, 9) that are arranged in the walls of the crankcase. At least one of said bearings is mounted in a passage hole (11) in a crankcase wall. The pump has a suction inlet separate from the crankcase. The pump (1) according to the invention is characterized in that at least one flow channel is provided in the crankcase wall for compensating pressure in the crankcase when the pump part oscillates and in that a flow damper is arranged in the at least one flow channel. In a preferred embodiment, the at least one passage hole having at least one bearing is configured as a flow channel.
