A pressure washer structured to output a pressurized fluid including an engine having a throttle plate structured to move between a closed position and a wide-open position, a pump driven by the engine and having an inlet and an outlet that discharges fluid, a spray gun having a spray gun inlet fluidly coupled to the outlet of the pump and a nozzle structured to discharge the fluid and having selectable nozzle orifices, and an electronic governor system structured to control a speed of the engine. The electronic governor system includes a carburetor, a motor coupled to the throttle plate to move the throttle plate between the closed and wide-open position, and a controller coupled to the motor to control the motor to control the speed of the engine in response to a selection of at least one of the one or more selectable nozzle orifices.

A mobile decontamination system has an internal combustion engine, a generator, a first pump, a boiler and a second pump. The engine is coupled to the generator and to the first pump. The first pump is designed for discharging a first decontamination medium via a first spray lance. The second pump is designed for discharging a second decontamination medium via a second spray lance. A system controller is designed for selectively operating the first pump and the heating boiler in one of at least two different operating modes. In the first operating mode, the first pump delivers a first volumetric flow through the boiler which is at such a high level that the first decontamination medium is in liquid form. In a second operating mode, the first pump delivers a second volumetric flow through the boiler which is at such a low level that the first decontamination medium transfers into gaseous form.

A modular design for a pressure washer system comprises a support frame including a top mounting surface, a first power assembly configured to be mounted to the support frame, and a cage assembly including a cage frame and a cage attached to the cage frame and configured to extend upwardly from the cage frame at least partially surrounding the power assembly, wherein the cage frame is configured to be attached to the support frame.

A pressure washer system comprises a cleaning fluid tank defining a cleaning fluid supply outlet, and a pump, engine and generator (PEG) unit including a pump defining a cleaning fluid pump inlet disposed vertically below the cleaning fluid supply outlet of the cleaning fluid supply tank.

The combustion chamber subassembly comprises a top bell member defining an interior combustion chamber and an exterior, the top bell member including a top diffuser wall, a first side wall extending from the top diffuser wall toward the interior combustion chamber of the top bell member, a second side wall extending from the first side wall toward the exterior of the top bell member, and a gasket that is attached to the top bell member, contacting the first side wall and the second sidewall.

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.

A system for cleaning industrial equipment is disclosed. The system includes a tank, a first pump, at least two burners, an outlet line, a self-cleaning filter, and a second pump. The tank stores a fluid. The first pump increase pressure on the fluid. Two burners increase a temperature of the fluid. The outlet line to applies the increased temperature and increase pressure fluid as a fluid flow to industrial equipment, which includes radiator fins. The self-cleaning filter configured to remove potential contaminants from the fluid. The second pump circulates fluid in the system.

A frame for a pressure washing device is provided. The frame comprises at least one tubular member and a plurality of bends are provided in the tubular member. The frame is preferably devoid of a support plate and is adapted to receive at least one of a power source and a pump that is directly mounted to the frame.

Low and medium pressure, high temperature, fluid washers for pressure cleaning surfaces, vessels, piping, tubing, and other structures having a tri-plex pump downstream of a fluid heater in which the high pressure pump employs a barrier seal system with circulating fluid.

An example cleaning system includes an engine, a high-pressure pump, and a clutch assembly. The clutch assembly selectively couples the engine to the high-pressure pump such that actuation of the electromagnetic clutch assembly controls a supply of power from the engine to the high-pressure pump. The system is controlled remotely.
