Invented in 1950 by Alfred Kärcher, who gave his name to the famous company making pressure washers, the operating principle of these tools was gradually improved in order to give birth to modern and now commonly used tools. Because water cannot be squeezed, when pressure is applied it will always naturally proceed to a zone of lower pressure. The pump can be an axial pump or a triplex pump. A pump powered by an electric motor mixes the detergent and the water together. =
If the fluid can move, when the pressure increases, the molecules have to move towards any point where the pressure is lower; in the case of the pressure washer that means through the outlet valve. 1

Most pressure washers follow this relatively simple model of operation: Detergent and water are drawn into the pressure washer through separate intake hoses. Unlike air, however, water cannot be compressed, so the crowding water molecules push against the walls of the container. This model from Karcher uses a water-cooled induction motor for extra efficiency. Pressure washers are part garden hose and part air compressor. eight
In order for the pumps to work correctly, they need water, which is provided, for example, by a garden hose [2]. Check out where the unloader is located on 3 different pressure washer pumps: As you can see the unloader is located on the exit side of the pump because it allows the pressurized water to flow back through the pump when it isn’t exiting into the high pressure hose (you’re not … Time limit is exhausted.
