Abstract
An anti-dry start device is provided for preventing the operation of a powered pressure washer in the absence of sufficient inlet fluid pressure, the device comprising a pressure switch removably mounted into a fitting installed in the inlet line to the pressure washer, the device further comprising an electrical interconnection between the pressure switch and an ignition system of the pressure washer, whereby the pressure switch is adapted to disrupt power to the pressure washer ignition switch when the inlet pressure is below a preset threshold.
Claims12
An anti-dry start device for preventing the operation of a powered pressure washer in the absence of sufficient inlet pressure, comprising:
- a sensor adapted to detect a level of fluid pressure at the inlet to the pressure washer;
- an electrical switching means interconnected to the sensor for responding to the detected fluid pressure level;
- and
- an electrical communication conduit interconnecting the switching means with the pressure washer so as to disable the pressure washer from operating when the detected fluid pressure is below a preset threshold.
An anti-dry start device for preventing the operation of a powered pressure washer in the absence of sufficient inlet pressure, comprising:
- a pressure switch having a pressure sensor and an electrical switching means;
- a pipe fitting having a first port adapted to be interconnected to a fluid supply, a second port adapted to be interconnected to the inlet of the pressure washer, and a third port adapted to receive the pressure switch;
- an electrical communication conduit interconnecting the switching means to an ignition system of the pressure washer so as to disrupt power to the pressure washer ignition system when the detected fluid pressure is below a preset threshold.
