Abstract
A submersible jet stream device having inlet apertures and an outlet nozzle which creates a jet stream which can be located either in a first position at the water surface or a second position at a pool bottom. The device may be hinged about a horizontal position for movement between the two positions. An embodiment may include two nozzles, one at each end of a housing and two propellers on a reversible motor disposed within the housing whereby the nozzle used for the flow is determined by the direction of motor rotation.
Claims15
A submersible jet stream device for a swimming pool, the device comprising a longitudinally extending housing having inlet-apertures and an outlet-nozzle extending substantially at a right angle to the housing, a flow-constricting necking situated between the inlet-apertures and the nozzle, an axial impeller rotatable by an underwater motor with said impeller being situated in the necking with its axis of rotation extending parallel to the longitudinal axis of the housing, the cross-sectional area of the necking having approximately the same surface as the outlet surface of the nozzle, characterized by having means for changing the position of the outlet nozzle between a first position near the water surface and a second position close to the bottom of the swimming pool.
Jet stream device for a swimming pool, the device comprising a longitudinally extending housing having inlet apertures and having an outlet nozzle at one end of the housing, a flow constricting necking situated between the inlet apertures and the nozzle, an axial impeller rotable by an underwater motor with said impeller being situated in the necking with its axis of rotation extending parallel to the longitudinal axis of the housing, the cross-sectional area of the necking having approximately the same surface as that of the outlet surface of the nozzle, characterized by a submersible housing, and means for pivoting the housing around a horizontal axis located approximately along half the height of the water level in the pool, so that the outlet nozzle in a first position is located near the water surface and in a second position is located near the bottom of the pool.
Jet stream device for a swimming pool, the device comprising a longitudinally extending housing having inlet-aperture and having an outlet-nozzle at one end of the housing near the water surface, a flow constricting necking situated between the inlet-apertures and the nozzle, an axial impeller rotable by an underwater motor with said impeller being situated in the necking with its axis of rotation extending parallel to the longitudinal axis of the housing, the cross-sectional area of the necking having approximately the same surface as that of the outlet surface of the nozzle, characterized in that means are provided for rotating the motor in either direction, that a second outlet nozzle is situated at the other end of the housing near the pool bottom, and there is a second propeller mounted on the shaft of said motor in a necking between the inlet apertures and the second outlet nozzle such that reversing the motor causes the jet stream to exit one of the other of said nozzles.
