Claim 3

The combination of claim 1 wherein said body includes an end wall on its end remote from said inlet port, said outlet port comprising a threaded bore formed generally centrally through said end wall, and a tubular reducer fitting threadedly engaged in said threaded bore.

Claim 4

The combination of claim 2 wherein said end wall includes a plurality of additional smaller diameter bores formed therethrough spaced circumferentially about said threaded bore.

Claim 5

The combination of claim 2 wherein said body includes elongated water flow disrupting means extending thereacross in registry with and closely adjacent the inlet end of said threaded bore.

Claim 6

The combination of claim 1 wherein said body includes an end wall on its end remote from said inlet port, said outlet port comprising a threaded bore formed generally centrally through said end wall, and a tubular reducer fitting threadedly engaged in said threaded bore.

Claim 7

The combination of claim 5 wherein said end wall includes a plurality of additional smaller diameter bores formed therethrough spaced circumferentially about said threaded bore.

Claim 8

The combination of claim 6 wherein said body includes elongated water flow disrupting means extending thereacross in registry with and closely adjacent the inlet end of said threaded bore.

Claim 9

The combination of claim 1 wherein said body comprises a substantially cylindrical body with said inlet and outlet ports opening into the opposite ends thereof, the opposite end portions of said cylindrical body including outer circumferentially extending grooves, and resilient ring members seated in said grooves and projecting radially outwardly of and circumferentially about the outer surface of said cylindrical body.

Claim 10

The combination of claim 1 wherein said body comprises a cylindrical body and said inlet and outlet ports open into the opposite ends of said body, said discharge ports comprising radial bores formed in said cylindrical body and arranged in circumferentially spaced rows of radial bores extending longitudinally of said body.

Claim 11

A pool cleaner for attachment to the discharge end of a flexible water supply hose disposed within a pool, said pool cleaner including an elongated hollow body defining a center axis and including opposite inlet and outlet end portions and a central portion disposed therebetween, said outlet end portion including water outlet means and said inlet end portion including water inlet means adapted for connection with the outlet end of said hose, said central portion of said body including discharge openings spaced thereabout and longitudinally therealong for discharging water from within said central portion outwardly of the latter, and water flow throttling means disposed within said central portion and movable in all transverse directions relative to said body, said water flow throttling means being positionable, by an imbalance of gravity forces acting thereon, to a position in a lower portion of said body to throttle the discharge of water from the lower discharge openings in said central portion, whereby the aggregate thrust forces acting on said body as a result of water being discharged from said discharge openings will be in a downward direction to thus maintain said cleaner in position at least closely adjacent the bottom of the associated pool.

Claim 12

A pool cleaner for attachment to the discharge end of a flexible water supply hose disposed within a pool, said pool cleaner including an elongated hollow body defining a center axis and including opposite inlet and outlet end portions and a central portion disposed therebetween, said outlet end portion including water outlet means and said inlet end portion including water inlet means adapted for connection with the outlet end of said hose, said central portion of said body including discharge openings spaced thereabout and longitudinally therealong for discharging water from within said central portion outwardly of the latter, and water flow throttling means disposed within said central portion and movable in all transverse directions relative to said body, said water flow throttling means being positionable, by an imbalance of gravity forces acting thereon, to a position in a lower portion of said body to throttle the discharge of water from the lower discharge openings in said central portion, whereby the aggregate thrust forces acting on said body as a result of water being discharged from said discharge openings will be in a downward direction to thus maintain said cleaner in position at least closely adjacent the bottom of the associated pool.

Claim 13

A water jet action pool cleaner for attachment to the discharge end of a flexible water supply hose disposed within a pool, said pool cleaner including an elongated hollow body having opPosite end inlet and outlet ports, said inlet port being adapted for connection with the outlet end of said hose, said body including discharge ports spaced circumferentially thereabout and longitudinally therealong for discharging water from within said body outwardly of the latter, and water flow throttling means movably disposed within said body for shifting to the lower portion of said body and including portions thereof registrable with the lower discharge ports in said body, said water flow throttling means being shiftable to a position in a lower portion of said body by an imbalance of gravity forces acting thereon and the registry of said portions of said water flow throttling means with the lower discharge ports in said body functioning to throttle the discharge of water from said lower discharge ports, whereby the aggregate thrust forces acting on said body as a result of water being discharged from said discharge ports will be in a downward direction to thus maintain said cleaner in position at least closely adjacent the bottom of the associated pool.

Claim 14

A water jet action pool cleaner for attachment to the discharge end of a flexible water supply hose disposed within a pool, said pool cleaner including an elongated hollow body having opPosite end inlet and outlet ports, said inlet port being adapted for connection with the outlet end of said hose, said body including discharge ports spaced circumferentially thereabout and longitudinally therealong for discharging water from within said body outwardly of the latter, and water flow throttling means movably disposed within said body for shifting to the lower portion of said body and including portions thereof registrable with the lower discharge ports in said body, said water flow throttling means being shiftable to a position in a lower portion of said body by an imbalance of gravity forces acting thereon and the registry of said portions of said water flow throttling means with the lower discharge ports in said body functioning to throttle the discharge of water from said lower discharge ports, whereby the aggregate thrust forces acting on said body as a result of water being discharged from said discharge ports will be in a downward direction to thus maintain said cleaner in position at least closely adjacent the bottom of the associated pool.
