The present invention is directed to a pressure washer having a main housing and a roll cage surrounding the main housing for protection. The roll cage is generally rectangular and provides flat surfaces to make it easier to store the unit, and importantly provides a flat top surface to allow other items to stack on top of the unit. The main housing also includes a storage compartment to store accessories, including a trigger gun. The trigger gun includes a trigger guard with openings to store additional nozzles for the gun.

A method of cleaning a converter, the method including the steps of: providing a heating unit for heating a cleaning fluid; providing a ring main for continuous circulation of heated cleaning fluid around the ring main; connecting the heating unit to the ring main; connecting the ring main to the converter to enable delivery of heated cleaning fluid to the converter; and providing a controllable cleaning fluid valve for delivery of a heated cleaning fluid, and providing a controllable rinsing fluid valve for delivery of a rinsing fluid; providing a controller for controlled delivery of a sequence of the rinsing fluid and the heated cleaning fluid to the converter upon recognition of a rinsing fluid delivery condition and a heated cleaning fluid delivery condition, respectively.

A hot water pressure washer employs an internal combustion engine with a drive shaft having an exhaust manifold fluidly connected to an exhaust water heat exchanger. The engine is driveably connected to a hydrodynamic heater, and a high-pressure pump for generating a stream of high-pressure fluid. The hot water pressure washer captures 80-90% of the thermal energy generated during combustion processes of the engine for heating water.

The notched base ring comprises a base ring sheet body including a top portion, a bottom portion, a first end connecting the top portion to the bottom portion, and a second end connecting the bottom portion to the top portion. The top portion includes a plurality of attachment lugs and defines a plurality of notches, each notch being at least partially defined by two lugs disposed on opposite sides of the notch, the top portion also including an angled top edge that is disposed at each of the attachment lugs, and the bottom portion includes a bottom support edge.

A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.

A rotor nozzle for a high-pressure cleaning apparatus is provided, with a housing having an inlet opening tangentially into the housing and an outlet arranged on an end wall and on which is arranged a pan-shaped, centrally broken recess. A nozzle body arranged in the housing, having a through channel, and supported with a spherical end in the pan-shaped recess has a longitudinal axis tilted toward the longitudinal axis of the housing. The nozzle body is brought into a revolving movement by liquid flowing through the housing and supported on a support surface, of which flow resistance elements, each having one baffle surface, are arranged downstream of on the wall of the housing. A guiding surface is arranged upstream of each baffle surface and is continuously adjoined by the baffle surface, wherein the guiding surface is aligned obliquely to a radial plane of the housing.

A pressure washer includes a pump for pressurizing a primary fluid flow, the pump including a pump inlet for receiving fluid from a common fluid source and a pump outlet for supplying a pressurized primary fluid and a jet pump including a primary fluid inlet fluidly coupled to the pump outlet, a secondary fluid inlet configured to receive fluid from the common fluid source, and a fluid outlet. In a high pressure operating mode, all of the pressurized primary fluid flows through the jet pump and exits through the fluid outlet of the jet pump. In a high flow operating mode, all the pressurized primary fluid flows through the jet pump and entrains a secondary fluid supplied through the secondary fluid inlet from the common fluid source so that the secondary fluid also flows through the jet pump, resulting in a combined fluid flow of the primary fluid and the secondary fluid that exits through the fluid outlet of the jet pump.

The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

In an embodiment, a pump assembly may include a mounting structure and a pump mechanism and a starter motor coupled to the mounting structure. The pump mechanism may include an input shaft configured to be rotatably coupled with an output shaft of a prime mover engine. The starter motor may be coupled with the input shaft of the pump mechanism for rotatably driving the input shaft of the pump mechanism.

This system was designed after many years of trying to resolve dirt and dust accumulation in confined areas on mobile and stationary equipment, and other types of plant equipment, including equipment of offshore oil and gas platforms, maritime vessels, and others, and more generally any kind of motorized or mechanical equipment with internal areas that accumulate dust and dirt. The areas where dust and dirt accumulation occur would normally only be accessible by removing major components. The initial installation of the wash system may be time consuming, however, may eliminate future risk exposure and manning. The system may be designed to utilize existing pressure washers and air systems. The supply manifold may be constructed from steel, hydraulic lines, pressure wash nozzles and angled fittings. The installer may assess areas of accumulation, directing the nozzles at the general area. Once the system has been installed, mechanical operators may easily attach the device to a pressure source. Quick connect fittings would be installed outside the machine, connecting pressurized water or air to the supply manifold.
