Abstract:
A hand-held suction pump for creating a vacuum in a container (2) provided with a suction valve (3), said pump comprising:an elongated outer casing in which an electric motor (7) and a piston pump (14, 15) driven by the motor (7) are accommodated; wherein the pump chamber (14) of the piston pump is connected by an inlet valve and a suction duct (28) to a hollow tip (34) at the free end of the casing for direct coupling with the suction valve of the container; the pump chamber being further connected by an outlet valve to an exhaust duct (29) having a duct opening on the outer surface of the wall of the outer casing for porting an exhaust flow to the exterior of the outer casing; characterized in that the duct opening of the exhaust duct (29) is overlapped by a baffle (38) which is separated from the outer surface of the wall of the outer casing so as to deflect the exhaust flow exiting the duct opening by a substantial angle.
