Claims22
A pneumatic pump for use in a vehicle, the pneumatic pump comprising
- a pump housing including a top casing and a bottom casing coupled to the top casing to define internal space therebetween,
- a fluid-driving system located in the internal space and configured to provide pressurized fluid, and
- a fluid regulator located in the internal space and coupled to the fluid-driving system to receive and direct the pressurized fluid,
- wherein the fluid-driving system includes a motor configured to rotate about a central axis, a diaphragm system including a plurality of diaphragms spaced circumferentially apart from one another around the central axis and configured to engage the fluid regulator, and an actuator plate coupled to the motor to move in response to rotation of the motor and coupled to the plurality of diaphragms to cause the plurality of diaphragms to move between a compressed state and an expanded stated in response to rotation of the motor.
