Abstract
A turbine assembly with directional control for use in a toy watercraft, including: a turbine housing defining an impeller cavity and including a forward opening and a rearward opening; a directional control valve positioned in the impeller cavity and having a valve opening in a sidewall thereof, the directional control valve being operable to rotate to a first position which closes the forward opening in the turbine housing and aligns the valve opening with the rearward opening in the turbine housing, and a second position which closes the rearward opening in the turbine housing an aligns the valve opening with the forward opening in the turbine housing; and a motor driven impeller positioned in the directional control valve.
Claims25
A turbine assembly for use in a toy watercraft, comprising:
- a turbine housing defining an impeller cavity and including a forward opening and a rearward opening;
- a directional control valve positioned in the impeller cavity and having a valve opening in a sidewall thereof, said directional control valve being operable to rotate to a first position which closes the forward opening in the turbine housing and aligns the valve opening with the rearward opening in the turbine housing, and a second position which closes the rearward opening in the turbine housing and aligns the valve opening with the forward opening in the turbine housing;
- and
- an impeller positioned in the directional control valve, wherein rotation of the impeller in a first direction causes the directional control valve to move to the first position and rotation of the impeller in a second direction causes the directional control valve to move to the second position.
A toy watercraft, comprising:
- a watercraft housing having a hull portion;
- a motor;
- a motor control system for selectively energizing the motor and
- controlling the direction of operation thereof;
- and
- a turbine assembly in the hull portion of the watercraft, including:
- a turbine housing defining an impeller cavity and including a forward opening and a rearward opening;
- a directional control valve positioned in the impeller cavity and having a valve opening in a sidewall thereof, said directional control valve being operable to rotate to a first position which closes the forward opening in the turbine housing and aligns the valve opening with the rearward opening in the turbine housing, and a second position which closes the rearward opening in the turbine housing and aligns the valve opening with the forward opening in the turbine housing;
- and
- an impeller operatively connected to the motor and positioned in the directional control valve, wherein rotation of the impeller in a first direction causes the directional control valve to move to the first position and rotation of the impeller in a second direction causes the directional control valve to move to the second position.
A toy watercraft, comprising:
- a watercraft housing having a hull portion;
- multiple motors;
- a motor control system for selectively energizing the motors and controlling the direction of operation thereof;
- and
- multiple turbine assemblies in the hull portion of the watercraft, wherein each turbine assembly includes:
- a turbine housing defining an impeller cavity and including a forward opening and a rearward opening;
- a directional control valve positioned in the impeller cavity and having a valve opening in a sidewall thereof, said directional control valve being operable to rotate to a first position which closes the forward opening in the turbine housing and aligns the valve opening with the rearward opening in the turbine housing, and a second position which closes the rearward opening in the turbine housing and aligns the valve opening with the forward opening in the turbine housing;
- and
- an impeller operatively connected to the motor and positioned in the directional control valve, wherein rotation of the impeller in a first direction causes the directional control valve to move to the first position and rotation of the impeller in a second direction causes the directional control valve to move to the second position.
