摘要： A jet pump housing is mountable to a hull of a personal watercraft. The jet pump housing comprises a body extending between an inlet and an outlet. The body has an inner wall delimiting an interior of the body and an outer wall. The inner wall and the outer wall are configured to be exposed to water during use of the personal watercraft. The body is shaped and sized to allow water to flow into the interior via the inlet and to expel water from the outlet. The body has one or more fluid passages positioned between the inner wall and the outer wall. The one or more fluid passages are fluidly isolated from the water and are in heat exchange relationship with the water via one or both of the inner wall and the outer wall.

摘要： A fuel system includes a fuel reservoir configured to be located within the fuel tank such that the fuel reservoir defines a fuel reservoir volume which is a subset of a fuel tank volume; a fuel pump configured to pump fuel from within the fuel reservoir volume to the fuel consuming device through a fuel supply line; a jet pump configured to 1) receive excess fuel, through a fuel return line, which had been supplied to the fuel consuming device through the fuel supply line and 2) aspirate fuel into the fuel reservoir volume from the fuel tank volume; and a valve which allows fuel flow in both directions between the fuel return line and the jet pump when a differential pressure across the valve is greater than or equal to a predetermined threshold.

摘要： Venturi devices and systems incorporating the same are disclosed. The Venturi devices include a lower body defining a passageway having a motive section and a discharge section spaced a distance apart from one another to define a first Venturi gap and a second Venturi gap downstream of the first Venturi gap at a position that divides the discharge section into a first portion between the first and second Venturi gaps and a second portion leading away from the second Venturi gap, and include an upper body defining a suction passageway in fluid communication with both the first and second Venturi gaps. The motive section and the discharge section converge toward the first Venturi gap.

摘要： An ejector with a suction nozzle is disclosed, with a drive nozzle and with a mixing tube, to which is assigned an adjustment device for the at least region-wise adjustment of a flow cross-section of the mixing tube. Inside the drive nozzle, an axially movable needle which is designed to adjust a flow cross-section of the drive nozzle is arranged and a coupling mechanism is provided which connects the adjustment device to the needle or to an actuator actuating the needle in such a way that the adjustment device adjusts or changes the flow cross-section of the mixing tube as a function of an axial needle movement. A fuel cell system with such an ejector is also disclosed.

摘要： A diagnostic apparatus for a powder coating material pump includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

摘要： Venturi devices for producing vacuum are disclosed that include a housing defining a motive port, a suction port, a discharge port, a first flow passage between the motive port and the discharge port, and a second flow passage into and through the suction port and into fluid communication with the first flow passage, a first check valve incorporated into the housing and positioned to control fluid flow through the suction port, and a sound attenuating wrap about the outer surface of the housing. The Venturi devices may also include a sound attenuating member disposed in the first flow passage downstream of the intersection of the second flow passage and the first flow passage, in the portion of the second flow passage leading into the suction port, in the first check valve, or combinations thereof.

摘要： An ejector includes a nozzle, a swirl flow generation portion, a body including a refrigerant suction port and a diffuser portion, a passage forming member, and an actuation device moving the passage forming member. A nozzle passage is defined between the nozzle and the passage forming member. A smallest passage cross-sectional area portion is provided in the nozzle passage. A swirl space that has a shape of a revolution and is coaxial with the nozzle, and a refrigerant inflow passage through which the refrigerant flows into the swirl space are defined in the swirl flow generation portion. The ejector further includes an area adjustment device that changes the passage cross-sectional area of the refrigerant inflow passage. According to this, an efficiency of energy conversion in the nozzle passage can be improved.

摘要： A marine jet pump with an adjustable venturi. An annularly compressible ring is affixed coaxially to the aft end of the pump housing. A collar coaxial to the ring is moveable coaxial to the ring. In a constricted mode the collar is mechanically forced over the aft end of the ring thereby reducing the diameter of the ring. In a dilated mode the collar is mechanically withdrawn to a predetermined degree from over the aft end of the ring allowing the ring to revert to it naturally dilated state. The transition between dilated mode and constricted mode can occur under full power.
