Abstract
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.
