US Patent:

55269869, Jun 18, 1996

Filed:

Mar 23, 1995

Appl. No.:

8/409284

Inventors:

David Padgett - Carlsbad CA
Robert J. Lind - Robbinsdale MN

Assignee:

Graco Inc - Minneapolis MN

International Classification:

B05B 500

US Classification:

239690

Abstract:

A voltage isolation device for controlling the flow of conductive liquid between a liquid supply source and a liquid destination source. The isolation device has an inlet connected to the supply source and has a yoke slide valve positionable along a pair of rods; one of the rods engages a slideable tube at the inlet to provide a liquid seal and the yoke slide valve may be positionable to slide the tube away from the rod to thereby provide a flow path for liquid through the tube and out the slide valve. A pair of seal assemblies each having axially spaced apart seals have formed sealing areas containing a non-conductive seal liquid which is capable of dissolving the conductive liquids being utilized. A scheme is provided to route arcs which result when the charged fluid is connected to the grounded fluid so as to locate the arc away from parts which could be damaged by it.

Abstract:

A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.
