Abstract

Abstract Apparatus for starting the engine of an automotive vehicle and only permitting the reengagement of the starter after interrupting the ignition and/or the feed of an injection pump associated with a switch provided with at least three successive positions inclusive of stop, ignition on and start positions, and opposing a second movement towards start position without first going towards the stop position. The apparatus comprises a turnable plate having an axis of rotation and adapted for controlling the operation of the switch of the starter circuit, the turnable plate having a circumferential groove therein extending substantially concentrically with respect to its axis. A stator faces the plate and has a blind bore therein in which a guide member is supported for free slidable and rotatable movement. An eccentric pin is secured to the guide member and extends therefrom into the groove. The groove has a widened terminal zone with three levels thereat, and the pin is engaged in the groove at the highest level in the stop position which is remote from the terminal zone. The pin travels at the highest level from one end of the groove to the other as the plate is rotated and passes successively from the stop position, to the ignition position and then to the start position. The plate then rotates in opposite direction whereupon the pin descends to the lowest level at a ''''running'''' position where the ignition remains on. A shoulder is provided between the lowest and middle levels to prevent return rotation of the plate from the lowest level to the middle level and hence direct return to the start position. The plate is turnable further in this opposite direction towards the stop position whereupon the ignition is cut and the pin rides onto the highest level of the groove so that the plate can new be returned to the start position.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 328 words
Apparatus for starting the engine of an automotive vehicle and only permitting the reengagement of the starter after interrupting the ignition and/or the feed of an injection pump associated with a switch provided with at least three successive positions inclusive of stop, ignition on, and start positions, the apparatus opposing a second movement to the start positions, without first going towards the stop position, said apparatus comprising a turnable plate having an axis of rotation for controlling the operation of the starter circuit of an automotive vehicle, said turnable plate having a circumferential groove therein extending substantially concentrically with respect to said axis, a stator facing said plate and having a blind bore therein, a guide member supported in said bore for free slidable and rotatable movement therein, an eccentric pin secured to said guide member and extending therefrom into said groove, said groove having a widened terminal zone with three levels thereat, said groove being at the highest level outside said terminal zone, said pin Being engaged in the groove at the highest level in teh stop position which is remote from said terminal zone, said pin traveling at said highest level from one end of the groove to the other as the plate is rotated and passing successively from the stop position, to the ignition on position and then to the start position, said plate then returning in opposite direction to an intermediate angular running position in which the ignition remains on and said pin descends to the lowest level, said groove having a shoulder between the lowest and middle levels to engage said pin and prevent return rotation of the plate directly from the running position to the start position, said plate being turnable further in said opposite direction from said running position towards said stop position whereupon the ignition is cut and said pin rides onto the highest level of the groove so that the plate can now be returned to the start position.
Claim 2
Dependent Claim 328 words
Apparatus for starting the engine of an automotive vehicle and only permitting the reengagement of the starter after interrupting the ignition and/or the feed of an injection pump associated with a switch provided with at least three successive positions inclusive of stop, ignition on, and start positions, the apparatus opposing a second movement to the start positions, without first going towards the stop position, said apparatus comprising a turnable plate having an axis of rotation for controlling the operation of the starter circuit of an automotive vehicle, said turnable plate having a circumferential groove therein extending substantially concentrically with respect to said axis, a stator facing said plate and having a blind bore therein, a guide member supported in said bore for free slidable and rotatable movement therein, an eccentric pin secured to said guide member and extending therefrom into said groove, said groove having a widened terminal zone with three levels thereat, said groove being at the highest level outside said terminal zone, said pin Being engaged in the groove at the highest level in teh stop position which is remote from said terminal zone, said pin traveling at said highest level from one end of the groove to the other as the plate is rotated and passing successively from the stop position, to the ignition on position and then to the start position, said plate then returning in opposite direction to an intermediate angular running position in which the ignition remains on and said pin descends to the lowest level, said groove having a shoulder between the lowest and middle levels to engage said pin and prevent return rotation of the plate directly from the running position to the start position, said plate being turnable further in said opposite direction from said running position towards said stop position whereupon the ignition is cut and said pin rides onto the highest level of the groove so that the plate can now be returned to the start position.
Claim 3
Dependent Claim 21 words
Apparatus as claimed in claim 1 wherein said groove has a ramp portion between said lowest level and the highest level.
Claim 4
Dependent Claim 23 words
Apparatus as claimed in claim 1 comprising elastic means acting on said guide member to urge the pin outwardly from said blind bore.
