Abstract
A mechanical fuel control governor employs a flyweight assembly for lifting the spindle of a fuel valve and allowing fuel to be bypassed from a high pressure line. The spindle is rotated via a fluid coupling between the ball head and the drive spindle such that the valve spindle rotates at a fraction of the ball head speed and whereby valve clearance and spindle leakage is reduced without reduction in the speed of the ball head.
Claims21
A governor for a power plant, said governor comprising:
- a valve connected in control relation to said power plant, said valve having a first member, and a second member with respect to which the first member rotates,
- driven means including a ball head supporting plural flyweights and responsive to the speed of said power plant for urging said flyweights radially outwardly by centrifugal force, the operation of said valve being governed by the radial position of said flyweights, and
- fluid coupling means providing a slip connection between said driven means and said first member so that said first member rotates at a speed less than that of said ball head.
A governor for a power plant, said governor comprising:
- a valve connected in control relation with said power plant, said valve including a tubular member and a spindle rotationally received therewithin,
- driven means including a ball head supporting plural flyweights responsive to the speed of said power plant for urging said flyweights radially outwardly by centrifugal force, and
- fluid coupling means between said driven means and said spindle for rotating said spindle at a speed less than that of said ball head.
A governor for a power plant, said governor comprising:
- a valve connected in control relation to said power plant, said valve including a ported tubular member and a spindle rotationally received therewithin,
- driven means including a ball head supporting plural flyweights responsive to the speed of said power plant for urging said flyweights radially outwardly by centrifugal force,
- a first disc operationally connected to said driven means for rotation in substantial synchronism with said ball head,
- a second disc disposed in face-to-face juxtaposition with said first disc, said second disc having a driving relation with said spindle, and
- means immersing said first and second discs in fluid to provide fluid coupling between said discs for rotating said spindle.

A governor for a power plant, said governor comprising:
- a valve connected in control relation to said power plant, said valve having a rotating member and a fixed member,
- driven means including a ball head supporting plural flyweights and responsive to the speed of said power plant for urging said flyweights radially outwardly by centrifugal force, the relative axial positions of said fixed and rotating members being governed by the radial position of said flyweights, and
- means providing a slip connection between said driven means and said rotating member so that said rotating member turns at a speed less than that of said ball head,
- wherein said means providing said slip connection comprises first and second discs immersed in a fluid and defining a fluid coupling therebetween, a first said disc being associated with said driven means and the second said disc being associated with said rotating member.

A governor for a power plant, said governor comprising:
- a valve connected in control relation with said power plant, said valve having a first member, and a second member comprising a spindle rotationally received within said first member,
- driven means including a ball head supporting plural flyweights responsive to the speed of said power plant for urging said flyweights radially outwardly by centrifugal force, and
- fluid coupling means between said driven means and said spindle for rotating said spindle at a speed less than that of said ball head,
