摘要： A pressure washer (110) includes a prime mover (114), a water pump (116), the water pump (116) including a pump inlet (128) for receiving fluid from a fluid source and a pump outlet (130) for supplying a pressurized primary fluid, a jet pump (200) including a primary fluid inlet (205) fluidly coupled to the pump outlet (130), a secondary fluid inlet (230), and a fluid outlet (225), and a spray gun (118) configured to be fluidly coupled to the fluid outlet (225) of the jet pump (200), the spray gun (118) including a spray gun outlet (265) having a variable effective flow area. Wherein, in operation, in a high pressure operating mode, the pressurized primary fluid flows through the jet pump (200) and exits through the fluid outlet (225) of the jet pump (205), and in a high flow operating mode, the pressurized primary fluid flows through the jet pump (200) and entrains a secondary fluid supplied through the secondary fluid inlet(230), resulting in a combined fluid flow.

摘要： 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.
