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.

The disclosure relates to a pressure cleaning device comprising a pressure generating unit for pressurizing a fluid and for dispensing a pressurized fluid via a hose attachment, preferably via a hand gun or via a cleaning nozzle. The pressure cleaning device can be operated in at least two different operating modes. According to the disclosure, a preferably electric pressure sensor for determining an actual operating pressure and/or a flow rate sensor for determining an actual flow rate and a control device are associated with the pressure generating unit. The control device is designed to control the pressure generating unit in particular, based on a respectively set operating mode in accordance with an actual operating pressure and/or an actual determined flow rate.

The subject invention provides yeast-based products, as well as their use to improve industrial production and performance by, for example, efficiently cleaning contaminating and/or fouling substances such as FOG, biofilm, paraffin, and/or asphaltenes from industrial equipment.

A mobile pressure washer can include a wheeled chassis, a power plant supported by the wheeled chassis, a fluid pump a fluid pump coupled to and driven by the power plant, a sprayer in fluid communication with the pump, a chemical solution container, and a container holder for supporting the chemical solution container. In some examples, the container holder has a frame operably connected to the wheeled chassis and has a container support mounted to the frame, the container support including a base wall and a sidewall defining a receptacle for receiving and supporting a container in fluid communication with the pump.

The steps of providing a cleaning device, a liquid proportioning device and a series of tanks filled with liquids. The cleaning device has a nozzle, a series of hoses and a pump. The liquid proportioning device includes a series of passageways, having three chambers and two valves, and a manifold for mixing the liquids to form a cleaning solution. The passageways include knobs to set the ratio of each liquid that the user desires to mix into a cleaning solution. Once the cleaning solution is mixed, it is fed through a pump to cleaning device for use. The proportioning device allows a user to easily, quickly and accurately mix liquids to form a cleaning solution.

A pressure washer system includes a fluid pump having a fluid inlet and a fluid outlet. A flow sensor is in fluid communication with one of the fluid inlet and the fluid outlet. An internal combustion engine is in driving communication with the fluid pump. A control module is mounted to the fluid pump. The control module is configured to receive an indication of flow through the fluid pump and to control a starting operation of the internal combustion engine to start the internal combustion engine in response to receiving the indication of flow through the fluid pump when the internal combustion engine is not running.

A portable vehicle washing assembly for automatically washing vehicles in a remote location includes a frame that includes a plurality of legs and a roof to have a vehicle drive beneath the frame. A plurality of first sprinklers is each of the first sprinklers is disposed on the frame to spray a liquid onto the vehicle. A plurality of second sprinklers is disposed on the frame to spray a liquid onto the vehicle. A first fluid pump is disposed on the support cage to pump a fluid and a liquid soap into the first sprinklers for washing the vehicle. A second fluid pump is disposed on the frame and the second fluid pump is in fluid communication with each of the second sprinklers to spray a mixture of the fluid and the liquid soap onto the vehicle for washing the vehicle.

The present invention relates to hand held apparatus which is for use in the provision of a supply of a liquid, such as water, which is emitted from the apparatus at a pressure which is greater than that at which it enters the apparatus and which apparatus is commonly referred to as a pressure washer. The invention is particularly, although not solely, related to the provision of the apparatus with a power supply which is mounted on the same and therefore renders the apparatus completely portable and the apparatus is provided with a pump, operating control means and features which allow a greater pressure of the liquid that is emitted to be achieved than is possible with conventional battery powered pressure water apparatus.

A pressure washer includes a main line through which, via a high-pressure pump, liquid can be conveyed to a spray opening, and a main valve. The main valve, when in a closed state, prevents liquid from flowing through the main line and, when in an open state, allows liquid to flow through the main line. The main valve is switchable between open and closed via an operator-controlled element. The main line has a suction chamber between the connection and the pump and a pressure chamber between the pump and the spray opening. The pressure chamber is fluidically connected to the suction chamber via a bypass line. A free cross-sectional area of the bypass line is settable via a bypass valve in the bypass line for regulating pressure in the pressure chamber. The bypass valve is adjustable via the operator-controlled element for setting the free cross-sectional area of the bypass line.

A handheld spray device has a flexible bellow coupled to a base to thereby retain liquid therein. The bellow has a bulbous section adjacent the base, narrows away from the base to terminal section opposite the base and has a side notch formed at one side of the bellow between the bulbous section and the terminal section. The base also has a nozzle therethrough such that when the bellow is squeezed in use, the liquid is forced via the nozzle.
