DIAPHRAGM PUMP AND LIQUID DISCHARGE APPARATUS INCLUDING DIAPHRAGM PUMP - A simplified explanation of the abstract

This abstract first appeared for US patent application 18348260 titled 'DIAPHRAGM PUMP AND LIQUID DISCHARGE APPARATUS INCLUDING DIAPHRAGM PUMP

Simplified Explanation

The abstract describes a diaphragm pump that consists of an actuator, a diaphragm, and two pump chambers. The diaphragm is bonded to the actuator and can deform to change the volume of the pump chambers, allowing fluid to flow. When the diaphragm is displaced convexly towards the first pump chamber, the second pump chamber expands and the first pump chamber contracts, causing fluid to flow into the second chamber and out of the first chamber. Conversely, when the diaphragm is displaced convexly towards the second pump chamber, the first pump chamber expands and the second pump chamber contracts, causing fluid to flow into the first chamber and out of the second chamber.

  • The diaphragm pump includes an actuator, diaphragm, and two pump chambers.
  • The diaphragm is bonded to the actuator and can deform to change the volumes of the pump chambers.
  • Fluid flows when the diaphragm is displaced convexly towards one of the pump chambers.
  • When the diaphragm moves towards the first pump chamber, the second chamber expands and the first chamber contracts, allowing fluid to flow into the second chamber and out of the first chamber.
  • When the diaphragm moves towards the second pump chamber, the first chamber expands and the second chamber contracts, allowing fluid to flow into the first chamber and out of the second chamber.

Original Abstract Submitted

A diaphragm pump includes an actuator, a diaphragm, and first and second pump chambers and deforms to change a volume of the first pump chamber and a volume of the second pump chamber so that fluid flows. The diaphragm is bonded to a first surface and a second surface of the actuator. When the diaphragm is displaced convexly in a direction to the first pump chamber, the second pump chamber is configured to expand and the first pump chamber is configured to contract so that fluid flows into the second pump chamber and fluid flows out of the first pump chamber. When the diaphragm is displaced convexly in a direction to the second pump chamber, the first pump chamber is configured to expand and the second pump chamber is configured to contract so that fluid flows into the first pump chamber and fluid flows out of the second pump chamber.
