Abstract
A cordless compressor has an air storage tank, a pump, a motor for driving the pump, and a controller circuit electrically connected to the motor. A pressure switch assembly is connected to the controller circuit. The pressure switch assembly has first and second pressure switches for sensing pressure within the air storage tank. The controller circuit controls de-activation of the motor depending upon status of the first and second pressure switches.
Claims3
A compressor comprising:
- an air storage tank;
- a pump for pressuring air within the air storage tank;
- a motor for driving the pump;
- a battery pack docking station electrically connected to the motor, wherein a power tool battery pack is electrically connectable to the battery pack docking station;
- a controller circuit electrically connected to the motor, the controller circuit determining a characteristic of the power tool battery pack electrically connected to the battery pack docking station;
- a pressure sensor connected to the controller circuit for sensing pressure within the air storage tank;
- a discharge port connected to the air storage tank;
- and
- a regulator disposed between the discharge port and the air storage tank;
- wherein the controller circuit adjusts a pressure threshold to de-activate the motor depending upon the determined characteristic of the power tool battery pack and the pressure sensed by the pressure sensor.
