Abstract

Abstract An actuator mechanism for the fuel quantity control member of a fuel injection pump includes an output member movable angularly by an electro-magnetic device, a radial arm pivotally mounted about the member and movable thereby by the intermediary of resilient means, the arm being connected to the control member through a link which is sufficiently stiff to transmit movement between the arm and the control member, but which can flex to permit variation in the paths of movement of the control member and the arm.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 136 words
An actuator mechanism for the fuel quantity control member of a fuel injection pump, the mechanism comprising an electromagnetic device having a radial arm extending from the device and being angularly movable about an axis proximal to one end of the device, a link pivotally connected proximal to the extended end of the arm, the link containing means for being rigidly mounted upon the control member of a fuel injection pump, and the link being flexible to permit variation in the paths of movement of the ends of the link so that when the link is connected to the control member of a fuel injection pump and the electro-magnetic device is activated for angular movement along with the radial arm connected thereto, the link will suitably flex and shift the control member in the desired manner.
Claim 2
Dependent Claim 136 words
An actuator mechanism for the fuel quantity control member of a fuel injection pump, the mechanism comprising an electromagnetic device having a radial arm extending from the device and being angularly movable about an axis proximal to one end of the device, a link pivotally connected proximal to the extended end of the arm, the link containing means for being rigidly mounted upon the control member of a fuel injection pump, and the link being flexible to permit variation in the paths of movement of the ends of the link so that when the link is connected to the control member of a fuel injection pump and the electro-magnetic device is activated for angular movement along with the radial arm connected thereto, the link will suitably flex and shift the control member in the desired manner.
Claim 3
Dependent Claim 139 words
An actuator mechanism for the fuel quantity control member of a fuel injection pump, the mechanism comprising an electro-magnetic device including an output member angularly movable about an axis and having a radial arm angularly movable about said axis adjacent one end of the output member, a link pivotally connected proximal to the extended end of the radial arm, the link having means for being rigidly mounted upon a control member of a fuel injection pump, and the link being flexible to permit variation in the paths of movement of the ends of the link so that when the link is connected to the control member of a fuel injection pump and the electro-magnetic device is activated for angular movement along with the radial arm, the link will suitably flex and shift the control member to the desired degree.
Claim 4
Dependent Claim 139 words
An actuator mechanism for the fuel quantity control member of a fuel injection pump, the mechanism comprising an electro-magnetic device including an output member angularly movable about an axis and having a radial arm angularly movable about said axis adjacent one end of the output member, a link pivotally connected proximal to the extended end of the radial arm, the link having means for being rigidly mounted upon a control member of a fuel injection pump, and the link being flexible to permit variation in the paths of movement of the ends of the link so that when the link is connected to the control member of a fuel injection pump and the electro-magnetic device is activated for angular movement along with the radial arm, the link will suitably flex and shift the control member to the desired degree.
Claim 5
Dependent Claim 24 words
An actuator mechanism as claimed in claim 2 in which said arm is mounted about said output member and is angularly movable relative thereto.
Claim 6
Dependent Claim 35 words
An actuator mechanism as claimed in claim 3 including resilient means acting to transmit movement of the output member to the arm in a direction to increase the amount of fuel supplied by the pump.
Claim 7
Dependent Claim 43 words
An actuator mechanism as claimed in claim 4 including a pair of pegs with one peg mounted on the arm and the other peg mounted on a member movable with the output member, said pegs being held in engagement by said resilient means.
Claim 8
Dependent Claim 39 words
An actuator mechanism as claimed in claim 5 in which said resilient means comprises a helical spring with one end of the spring engaged with one peg and the other end of the spring engaged with the other peg.
Claim 9
Dependent Claim 25 words
An actuator mechanism as claimed in claim 6 including spring means acting on said member in opposition to the force exerted by said electro-magnetic device.
Claim 10
Dependent Claim 39 words
An actuator mechanism as claimed in claim 1 including a stop lever engageable with an abutment carried by the control member to move the control member in a direction to reduce the amount of fuel supplied by the pump.
Claim 11
Dependent Claim 32 words
An actuator mechanism as claimed in claim 8 in which said member forms part of a transducer for providing a signal indicative of the position of the control member of the pump.
