A gear reduction assembly ( ) located in the housing includes a gear reduction mechanism ( A) and impeller ( B) located near the inlet port and connected to a rotary input shaft of the gear reduction mechanism ( A). A cam device ( ) engages a rotary output shaft of the gear reduction mechanism so as to rotate the cam device in response to rotation of the impeller. The cam device ( ) includes a raised section ( A having their own a raised camming surface ( B) which rotates in response to rotation of an impeller of the impeller ( B). A plurality of valve assemblies disposed in the lower section ( A) are arranged to open or close fluid paths through the plurality of fluid outlet ports ( ), respectively, in response to rotation of the camming surface ( B). Each valve assembly includes a valve seat in the corresponding fluid outlet port, and a hinged valve plate ( ) in the lower section ( A) connected to contact the valve seat so as to close the outlet port and to move away from the valve plate to open the outlet port.

International Classification:

US Classification:

Abstract:

A swimming pool debris removal system includes a recirculating pump and a vacuum chamber having an access port, an inlet port, and an outlet port connected to a suction inlet of the pump. The inlet port is connected to receive water and debris pumped from the pool. A removable vacuum seal lid is disposed in the access port, forming a vacuum seal therewith. An air bleed tube coupled to the outlet port draws air trapped between the lid and water in the chamber into the outlet port and suction inlet when the pump is operating, causing the trapped air to be replaced by water and thereby reducing momentum forces of water in the chamber against the lid as the pump is turned off. The lid includes a disk with a circumferential groove and a handle attached to an upper surface of the disk. A resilient seal ring co-molded with the disk is attached to the plastic disk and disposed around a circumferential portion of the disk, and includes a base portion that engages the circumferential portion and is partially disposed in the first circumferential groove. The resilient seal ring also includes an inclined flange portion that extends outward and upward from the circumferential portion to provide slidable, vacuum sealing engagement with the access opening.

Abstract:

A system for automatically maintaining a desired water level in a swimming pool, includes a float chamber coupled in fluid communication with a suction tube that is coupled between the pool and a pool filter pump. A float carrying a magnetic element is disposed in the float chamber. A magnetic switch is located in a fixed position outside of the float chamber at a level corresponding to the desired water level. The magnetic switch assumes a first state if the pool water level is equal to or higher than the desired water level and assumes a second state if the pool water level is lower than the desired water level. A solenoid valve is connected between a pressurized water source and an intermediate portion of a return tube returning pumped water to the pool. A circuit is coupled to the valve and the magnetic switch to close the valve when the pump is operating, and open the valve when the pump is not running and the magnetic switch is in the second state.
