摘要： An apparatus (102) includes a pump body (124), two or more arms (120,122) extending from the pump body (124) configured to hold a cement mixing container (104), a vacuum port (230) exposed on an exterior surface of the pump body (124) and positioned to engage a port on the cement mixing container (104), a venturi (324) positioned proximate the vacuum port (230); a perforator (320) within the pump body (124), the perforator (320) configured to puncture a gas container (314) to release gas to the venturi (324) to create a vacuum at the vacuum port (230); and an actuator (126) configured to puncture the gas container (314) with the perforator (320).

摘要： A pump for both filling and emptying containers with liquids, flowable solids, etc. has a body (20) which is screwed into a bung hole (15) in the top wall of the container. According to the state of evacuation or pressurisation produced in the container by the pump, "liquid" will enter or leave the container via pipe (21) passing through the body (20) of the pump. The motive power for the pump is a compressed air source (14) which provides air to a venturi (31) positioned in a passage (24) connecting the interior of the container with the exterior via vented (27) chamber (25). Air flowing through air ports (32) in the venturi generates a vortex which creates air flow through passage (24). By turning handle (29) the venturi may be rotated so as to reverse its orientation and thus reverse the direction of air flow to either pressurise or evacuate the container. Alternatively a pair of oppositely-directed venturis selectively connectable to air passage (24) may be used to perform the emptying and filling functions.
