Pneumatic pump

A pneumatic pump for use in a vehicle, the pneumatic pump comprising

• a pump housing including a top casing that has a downward-facing surface, a bottom casing coupled to the top casing and having an upward-facing surface, and a side wall that extends from the top casing toward the bottom casing and has an inward-facing surface that extends circumferentially around a central axis, the pump housing to define formed to include an internal space defined at least in part by each of the downward-facing surface, the upward-facing surface, and the inward-facing surface,
• 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 hollow, cylindrical actuator having an angled top surface configured to rotate about the central axis, a diaphragm system including a plurality of diaphragms arranged on a horizontal reference plane that is perpendicular to the central axis and is arranged to extend through the hollow, cylindrical actuator and each of the plurality of diaphragms, each of the 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 actuator and coupled to the plurality of diaphragms to cause the plurality of diaphragms to move between a compressed state and an expanded state in response to rotation of the actuator.
