  • Patent number: 5142714
    Abstract: A nozzle assembly for discharging a mixture of first and second fluids includes a housing having inlets for introducting the first and second fluids into the housing; and a sleeve disposed in and affixed to the housing and receiving the second fluid from one of the inlets. There is further provided a holding ring disposed in the housing and surrounding the sleeve. The holding ring may be displaced relative to the sleeve in a direction parallel to the sleeve length. A nozzle body is situated in the housing and has a spherical member surrounding the sleeve and a nozzle outlet member. The nozzle body has a sealing face situated inside the spherical member and cooperating with a spherical sealing face of the sleeve for determining therewith a variable annular gap constituting a flow passage area for the first fluid. The nozzle body is held captive in the holding ring and may pivot therein. The nozzle body and the holding ring move substantially as a unit upon longitudinal displacement of the holding ring.

  • Patent number: 5012535
    Abstract: A tub including a fluid system has a pump which includes a suction side and a pressure side; a nozzle for introducing a water-and-air mixture into the tub; the nozzle having a nozzle portion; a pressure line connecting the pressure side of the pump with the nozzle portion; a suction opening provided in a bottom region of the tub; and a suction line connecting the suction side of the pump with the suction opening. The fluid system further has a valve provided in the nozzle portion for cutting off fluid flow to the tub; an overflow line having a closable vent opening and being coupled to the suction side of the pump; a device for selectively allowing or blocking fluid communication between the overflow line and the suction line of the pump; and a supply source for introducing a cleaning agent at a location upstream of the nozzle as viewed in a direction of fluid flow therethrough.
