摘要： A backflush conduit (38) for an automatic backflushing filter (10) having an inlet portion (62) with a symmetrical converging bell-shaped cross section, an outlet portion (60) with a generally cylindrical shape, and a converging and reorienting transition portion (64) connecting the inlet and outlet portions. Converging convex surfaces (66, 68) of the bell-shaped opening (62) smooth fluid inflow and prevent fluid separation. The transition portion (64) interior contour redirects the fluid flow without inducing turbulence, resulting in more efficient backflushing to clean the entire filter element (26) even at small element pore sizes.

摘要： An actuator for actuating a valve (16) from a first position to a second position includes a housing (14) and a rotatable stem (70) mounted within the housing and restricted from moving axially. The actuator also includes a non-rotatable plunger (94) engaging the stem such that the plunger moves axially in response to rotation of the stem, whereby the valve is actuated from the first position to the second position. The actuator is also provided with a non-rotatable indicator member (38), which is mounted within the housing and through which the stem extends. The indicator member engages the stem such that the indicator member moves axially in response to rotation of the stem. A viewing window (60, 64) is formed in a wall of the housing such that the indicator member can be seen through the window for indicating the first position and the second position of the valve.

摘要： A fluid filter (10) having a hollow, molded, plastic housing (12) with an open end, a fluid inlet port (20) and a fluid outlet (22). An internally threaded, plastic, molded cap (14) is threadedly received on the housing (12) via mating external threads (56, 58) for sealing the open end of the housing (12). A cap seal (60) prevents fluid contamination of the threads (56, 58). A removable filter element (38) is contained within the housing (12) between the fluid inlet (20) and the fluid outlet (22). A molded, resilient, plastic retainer (44) captured between the cap (14) and the filter element (38) retains the filter element (38) in position within the filter (10). If the filter element (38) is of a bag filter type, as compared with a filter cartridge type, the retainer (44) has a plurality of resilient legs (46) which press down upon a bag mouth seal (40) forcing it into contact with a flared mouth of the bag support (28).

摘要： A fluid heater includes a housing (12), a burner unit (24) disposed in a bottom portion of the housing (12) for burning combustible fuel, a combustion chamber (48) disposed within the housing (12) where the fuel is burned and a heat exchanger (68) disposed substantially within the housing (12) over the combustion chamber (48). The heat exchanger (68) absorbs heat generated from burning the fuel and conducts the heat to a fluid to be heated. The heat exchanger (68) includes a pair of spaced, parallel, stainless steel tubesheets (72, 74) with a plurality of tubes (70) running therebetween and sealingly received within mating apertures in each of the tubesheets (72, 74). A plastic front header (78) and a plastic rear header (76) are removably attached to the tubesheets (72, 74) distal to said tubes (70). The apertures (112) in the tubesheets (72, 74) preferably have forged flanges (114) for increasing the surface contact area with the heat exchanger tubes (70). The heat exchanger (68) is corrosion resistant due to the combination of corrosion-resistant tubesheets (72, 74), tubes (70) and headers (76, 78).

摘要： A suction nozzle (28) adapted for use in a suction cleaning device (10), such as an automatic swimming pool cleaner, includes a body (30) having a throat (32) extending from an inlet (24) at one end of the body (30) to an outlet (34) at an opposite end of the body (30). The body (30) itself is split longitudinally into a plurality of discrete body portions (36, 38) to form the throat (32) of the nozzle (28). One body portion (38) is movable relative to the other body portion (36), whereby the throat (32) automatically expands in response to the relative movement of the body portions (36, 38). The resulting expansion of the nozzle (28) allows substantially unrestricted passage of large foreign objects (B) through the throat (32) during the operation of the suction cleaning device (10).

摘要： A safety device (34) for use in a suction outlet assembly (10) of a swimming pool (12), whirlpool, spa or the like is disclosed. More particularly, the outlet assembly has an opening (22) therein in communication with a pump (24) adapted to create sufficient suction for causing fluid flow through the outlet assembly and a cover (30) mounted over the opening without substantially obstructing fluid flow therethrough. The safety device includes an obstructing mechanism (38) for obstructing the opening when the cover is not properly positioned or affixed to the outlet assembly, whereby fluid flow through the outlet assembly is substantially prevented even if the pump is in operation.

摘要： A device for filtering fluid includes a hollow housing (10) having a fluid inlet (26) and a fluid outlet (28). A filter element (50) formed of fluid permeable material is disposed within the housing (10) for filtering fluid entering the fluid inlet (26), the fluid passing through the element (50) and out the fluid outlet (28). The element has a generally cylindrical configuration with the permeable material forming a plurality of elongated, radially extending pleats (98). The pleats are supported by spacers (81) having a plurality of blades (102) attached to a web (106) with channels (104) therebetween. The element (50) is used as a septum for supporting a diatomaceous earth precoat. A regeneration piston (76) creates fluid flows within the filter that cause the element (50) to flutter, thereby displacing the diatomaceous earth precoat from the septum for regeneration.
