Autonomous vacuum pump
11623192 · 2023-04-11 · ·

An apparatus includes a pump body, two or more arms extending from the pump body configured to hold a cement mixing container, a vacuum port exposed on an exterior surface of the pump body and positioned to engage a port on the cement mixing container, a venturi positioned proximate the vacuum port; a perforator within the pump body, the perforator configured to puncture a gas container to release gas to the venturi to create a vacuum at the vacuum port; and an actuator configured to puncture the gas container with the perforator.
