Abstract: A distribution valve of an in-floor pool cleaning system is provided. The distribution valve includes a housing having an inlet port and a plurality of outlet ports. A turbine within the housing rotates about a shaft in response to fluid flowing through the inlet port. The turbine is releasably coupled to a gear mechanism, and the gear mechanism is releasably coupled to a distribution valve disk, the disk having an aperture therein. As the turbine rotates, the gear mechanism also rotates and drives the rotation of the disk around the shaft. The rotation of the disk sequentially places the aperture over one of the plurality of outlet ports, thus allowing fluid to flow out of the outlet port over which the aperture is positioned, but restricting fluid flow into any of the outlet ports that are covered by the disk.

Abstract: A cleaning head for an in-floor pool cleaning system includes a sleeve with a top opening and an insert configured to be retained within the sleeve. The insert has a first body portion with an aperture wherein the first body portion is configured to fit through the top opening, and a second body portion that is configured to not fit through the top opening. A passage runs through the insert to the aperture. The insert has a first position in which it is retained in the sleeve. When water pressure is applied to the bottom of the cleaning head, the insert is moved upward to a second position so the aperture extends beyond the top opening in the sleeve and pressurized water exists the aperture to move debris. The cleaning head also includes a conical spring to bias the insert towards the first position.

Abstract: Disclosed is a valve for use in in-floor pool cleaning systems. The valve has a housing with an inlet port, an internal cavity and multiple outlet ports. A drive source, which can be an impeller positioned in the cavity and in fluid communication with the inlet port, is directly or indirectly (such as by a gear assembly) connected to a fluid control plate that has one or more apertures. As fluid enters the cavity through the inlet port the drive rotates the fluid control plate. As the plate rotates the aperture(s) rotate to allow the fluid to pass through the aperture(s) and into the respective outlet ports.

Abstract: A venturi-type liquid pump is provided. The pump includes a supply line having a front end and a rear end, wherein the front end of the supply line includes a connector for connecting a supply of pressurized liquid to the supply line and the rear end of the supply line includes a nozzle having an exit orifice through which the pressurized liquid exits the supply line. The pump further includes a suction line having a first end and a second end, wherein the suction line is positioned in relation to the supply line to define a gap between the exit orifice and the first end such that the pressurized liquid exiting the exit orifice traverses the gap and entrains a second liquid within the gap before entering the first end of the suction line together with the entrained second liquid.
