Abstract

This automatic device for the putting in place of the valves of an internal combustion engine serves to insert half cones in a collar on the valve stem. Within a housing provided with a cover it comprises: a central slide displaceable in the direction indicated by the arrow A between a withdrawn position and a position of presentation of the double cones arranged on each side of the slide; a pair of jaws sliding on shafts, which jaws are spread apart when the slide is in presentation position, each jaw receiving a lever adapted to hold a half cone in its lower part and to push it towards the inside; and push means cooperating with the collar in order to compress the valve spring in synchronism with the movement of the slide. This device operates whatever the inclination of the valve. Due to their small overall dimension, several devices can be placed alongside of each other.

Dependent claims

A device for automatically placing valves of an internal combustion engine by inserting half cones in a collar on a valve stem, said device capable of accomomdating valves having one or more grooves, said valve stem being disposed on a vertical or inclined axis, wherein said device comprises:

pushing means adapted to cooperate with the collar in order to compress a valve spring on the opposite side of the collar so as to expose said valve stem;
a pair of jaws laterally displaceable along an axis perpendicular to said valve stem, said pair of jaws adapted to cause grasping of said half cones regardless of the inclination of the valve stem with respect to the vertical axis;
and
a central slide vertically displaceable between an extended and a retracted position, said central slide including means for controlling said lateral displacement of said jaws, a lower portion of said central slide adapted to maintain said half cones in a spread apart position.
