Abstract
An improved rotational speed governor characterized by a non-linear response to speed changes, includes a control arm, the angular position of which changes in response to the rotational speed of the governor, the control arm carrying a weight held to a fixed position with respect to the control arm at speeds less than a first predetermined speed and displaced from said control arm by centrifugal force at speeds greater than that predetermined speed to effect a non-linear pivotal displacement response to the control arm.
Claims11
A governor providing actuation of a body in response to the rotational speed of said governor, said governor being characterized by:
- a control arm connected to said body and pivotable about an axis therethrough, said body applying a restoring force to said control arm,
- a weight, carried by said control arm and under conditions of centrifugal loading thereof, due to rotation of said governor, being urged outwardly along a path extending from an outer end of said control arm toward the plane of rotation of said body thereby pivotally biasing said control arm in a direction opposite that of said restoring force, and
- means carried by said control arm for restraining said weight in a fixed position with respect to said control arm at rotational speeds less than a first predetermined speed and accommodating centrifugal loading of said weight at rotational speeds greater than said first predetermined speed by displacement of said weight relative to said control arm, said centrifugal loading of said weight at speeds less than said predetermined speed overcoming said restoring force to effect pivoting of said control arm in one direction, said centrifugal loading at selected speeds greater than said predetermined speed being overcome by said restoring force thereby causing pivoting of said control arm in a direction opposite said one direction.
A governor providing actuation of a body in response to the rotational speed of said governor, said governor being characterized by:
- a control arm connected to said body and pivotable about an axis therethrough,
- a weight carried by said control arm by pivotal mounting thereon, said weight being urged outwardly under the influence of centrifugal force acting thereon under conditions of rotation of said governor thereby pivotally biasing said control arm, and
- a preloaded resilient means carried by said control arm and connected to said control arm and said weight for restraining said weight in a fixed position with respect to said control arm at rotational speeds less than a first predetermined speed and accommodating centrifugal loading of said weight at rotational speeds greater than said first predetermined speed by displacement of said weight relative to said control arm.
