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.

A jet pump comprising a pump housing containing a jet nozzle and a throat diffuser nozzle. The jet nozzle is comprised of a jet nozzle insert disposed in an axial inner bore of a precision jet cylindrical body and formed of an ultra-hard material. The throat diffuser nozzle is comprised of a throat diffuser nozzle insert disposed in an axial inner bore of a precision throat diffuser cylindrical body and also formed of an ultra-hard material. The jet nozzle and throat diffuser nozzle are disposed in an elongated cylindrical central bore portion of a tubular side wall of the pump housing. In order to achieve highest concentricity of the axial inner bores, the axial inner bore of the jet nozzle insert and the axial inner bore of the throat diffuser nozzle insert are formed after placement in the precision cylindrical bodies.

The present invention provides a booster apparatus (10) for entraining gas in a flowing second fluid. The booster apparatus comprises a booster housing (116) for receiving a fluid. The booster apparatus has at least one inlet (123) through which a first fluid passes to be entrained in the second fluid when the second fluid is flowing through the booster housing. The present invention also provides a booster assembly (12) comprising a booster apparatus (10) and a fluid motive mechanism such as a turbine unit (11).

Slip joint clamps seat on a diffuser end via external features of the diffuser, like guide ears, regardless of slip joint wear or damage. The clamps can be opened and closed to surround an inlet mixer forming a slip joint with the diffuser without disassembly. Slip joint clamps drive or bias the inlet mixer in a lateral direction largely perpendicular to the axial orientation and end of the diffuser to achieve a desired preload force in the inlet mixer and clamp connection. Clamp arms include rotatable halves that, when joined, form a complete fill between an inner surface of the diffuser and outer surface of the inlet mixer. A lateral drive pushes the inlet mixer against the clamp and may include a resistive element. An accessible set of guide ear bolts and lateral driving bolts permit exterior manipulation to axially mount or laterally bias the clamp in the slip joint.

The invention relates to a jet pump collector comprising a convergent duct extending along the longitudinal axis (AX) and comprising an intake opening for a fluid to be withdrawn, this convergent duct having a restriction shape terminated by a reduced end having a smaller cross-section than its intake opening. This convergent duct is equipped with a tube (17) orientated perpendicular to the longitudinal axis longitudinal (AX), this tube (17) comprising an outer portion extending outside of the convergent duct and being terminated by an intake opening (31) for a propulsion fluid, and an inner portion extending in the convergent duct and comprising a plurality of distribution openings (18, 19) for the propulsion fluid which are orientated towards the reduced end.
