[origin: US5788464A] PCT No. PCT/EP94/03248 Sec. 371 Date Jul. 19, 1996 Sec. 102(e) Date Jul. 19, 1996 PCT Filed Sep. 29, 1994 PCT Pub. No. WO95/09985 PCT Pub. Date Apr. 13, 1995The device and process for suction in a fluid medium are based on a special arrangement of a driver pump (2) and a jet pump (1) which preferably provide excellent suction with compact dimensions. The driver pump (2) supplies the fluid medium under pressure to the jet pump (1). The desired suction is obtained via an suction slot (3) in the jet pump (1). The driver pump (2) conveys the fluid medium required to operate the jet pump (1) via an inlet (9) which does not feed the suction slot (3).
