摘要:
A multiple outlet valve includes a valve actuating mechanism driven by a turbine. Fluid entering the valve passes through a flow control member which determines the velocity of the fluid entering the turbine and thereby controls the frequency with which the valve operates. The valve further includes a gasket associated with a valve shut-off plate for preventing leakage of fluid between outlet chambers in the base.

A swimming pool hydraulic suction fuse system. Implementations may include a fuse housing having a pump outlet, a drain inlet, and an air source. The hydraulic suction fuse system may also include a fuse assembly coupled into the fuse housing, the fuse assembly having a fuse body including a first section and a second section. An air intake may be coupled to the fuse body and a magnet assembly may be coupled to the first section of the fuse body. The magnet assembly may include a solid magnet. A fuse may be included, which may be coupled to the second section of the fuse body and include an attractor element coupled between a fuse cap and a fuse stem.

The swimming pool floor or spa floor drain assembly of the present invention includes a drain body having a mouth positionable in proximity to the pool wall to serve as a fluid flow inlet, a spaced apart fluid flow outlet positionable below the mouth and a sidewall interconnecting the mouth with the outlet to define a fluid flow chamber. The cross sectional area of the fluid flow chamber decreases from the mouth to the base. A fluid deflecting plug includes a comparatively large area top and a comparatively small area base. A sidewall interconnects the top and base to form the plug with a cross sectional area decreasing form the top to the base. A support structure positions the plug within the drain body such that at least a substantial portion of the plug sidewall is spaced apart from the drain body sidewall to define a fluid flow channel having a first comparatively larger cross sectional area in proximity to the drain body mouth and a second comparatively smaller cross sectional area in proximity to the drain body outlet. The variation in the cross sectional area from the drain body mouth to the drain body outlet provides a lower fluid flow velocity at the mouth than at the outlet when fluid is transferred from the pool through the floor drain assembly.

Methods of relieving the suction force in a swimming pool or spa. A first method may include the steps of closing an aperture in a hydraulic suction fuse through magnetic force and opening the aperture by increasing suction force within the hydraulic suction fuse. Implementations of hydraulic suction fuses may also utilize a method of adjusting the fuse point of a hydraulic suction fuse. The method may include decoupling a magnet assembly from a first step having a first height, the first step contained in a fuse body contained in the hydraulic suction fuse. The method may also include rotating the magnet assembly and coupling the magnet assembly with a second step having a second height, the second step contained in the fuse body.

Methods of cleaning a swimming pool using a swimming pool cleaning head. A first method may include intermittently raising a nozzle head under water and ejecting a stream of water under water, incrementally rotating the nozzle head in a clockwise direction, retracting the nozzle head, sliding a cam reverser, and reversing the direction of rotation of the nozzle head with the cam reverser to counterclockwise. A second method may include rotating a stem by sliding at least one pin coupled to the stem through at least one channel in a cam, the stem configured to release a stream of water under water in a swimming pool. The method may further include reversing the direction of rotation of the stem by sliding a slidable section of the cam with the at least one pin.
摘要:
A protruding nozzle assembly, mounted in a side wall of a swimming pool in communication with a source of water, will eject through a nozzle of a nozzle housing a stream of water at a predetermined angle relative to the adjacent side wall surface. During each erection and retraction of the nozzle housing precipitated by initiation and cessation of water flow to the nozzle assembly, the nozzle housing will rotate incrementally to provide a plurality of streams of water defining a fan-like area from each nozzle as such nozzle comes into fluid communication with an opening in a cover enclosing the nozzle housing. Each nozzle is canted to a different angle above the adjacent surface to assist in cleaning sloping parts of the side wall/bottom surface junction and to assist in cleaning any adjacent structures extending from the side wall.

A swimming pool water leveler system. Implementations may include a water leveler comprising one or more of the following aspects: separate fill and sensing chambers within the water leveler housing; logical water level adjustment features that provide a tactile indicator of water level change; a continuous balance line and overflow line; a water supply line seal valve with a cup seal; a reducer plug in an outlet between the sensing chamber and the balance line to assist in junk removal; and the ability to pressure test the balance line and overflow line at the same time.

A removable retainer for holding a nozzle stem in a body has opposed indentations for receiving the tines of a forded tool. The periphery of the retainer and the inner edge of the body are relieved to receive and guide the tool tines to the indentations.

A swimming pool pop-up fitting having a pop-up head responsive to the intermittent application of water under pressure to reciprocate between retracted and projected positions for directing a jet of water over the adjacent inner surface of a swimming pool from a nozzle in the head.The pop-up fitting includes a fixed retainer having cams that are engageable by camming pins carried by the nozzle head to incrementally rotate the head during its movement between retracted and projected positions. The pins can be removed and the head constrained against rotation to convert the head from a rotary head to a pop-up head which is rotationally stationary or fixed.The pop-up head includes a stem which mounts the nozzle. The nozzle has diametrically opposed nozzle openings which are selectively alignable with an opening in the stem. Location of an insert in one of the nozzle openings reduces its diameter so that selective positioning of the nozzle insert adjacent the stem opening converts the fitting from a high water flow rate to a lower water flow rate.The nozzle is retractable into a relatively large diameter nozzle recess located above a smaller stem recess which receives the stem. The wall defining the nozzle recess is provided with camming surfaces or cams which, because of the ample space available, are made relatively large and consequently more durable and more sensitive to the camming action of the nozzle pins. Also, location of the cams in the large nozzle recess presents a minimum obstruction to water flow and promotes higher water flow rates through the fitting.
