Abstract
A timing device for an axial engine comprising for each valve a return spring, a rocker arm and a push rod actuated by a cam. Each rocker arm is pivotably mounted in a rocker arm carrier which is itself mounted so that it can slide in a direction perpendicular to the corresponding valve stem and the position of which in this perpendicular direction is maintained by means of an externally controlled regulating element which actuates this rocker arm which bears on a push rod and the valve stem.
Claims10
In an axial internal combustion engine having a casing containing at least one valve movable in a first direction, a return spring for each said valve, a cam actuated push rod of each said valve and a rocker arm connecting each said valve with one said push rod, a timing device comprising:
- a rocker arm carrier in said casing for each said rocker arm, each said rocker arm being mounted in one said rocker arm carrier, each said rocker arm carrier being movable in a direction perpendicular to said first direction;
- a fixed annular piece in said casing, said annular piece having two parallel cylindrical seatings for each said valve, said cylindrical seatings including longitudinal axes which are perpendicular to the axis of said axial engine, said annular piece further having a bore connecting said two seatings, wherein said rocker arm carrier and said push rod are each positioned in one of said seatings, and said rocker arm is positioned in said bore;
- and
- regulating means engageable with said rocker arm carrier for adjustably maintaining the position of said rocker arm carrier in said first direction, an adjusting portion of said regulating means extending outside of said casing.
In an axial internal combustion engine having a casing containing at least one valve movable in a first direction, a return spring for each saiid valve, a cam actuated push rod of each said valve and a rocker arm connecting each said valve with one said push rod, a timing device comprising:
- a rocker arm carrier in said casing for each said rocker arm, each said rocker arm being mounted in one said rocker arm carrier, each said rocker arm carrier being movable in a direction perpendicular to said first direction;
- and
- regulating means engageable with said rocker arm carrier for adjustably maintaining the position of said rocker arm carrier in said first direction, an adjusting portion of said regulating means extending outside of said casing,
- wherein said push rod has two parallel flat portions having surfaces parallel to the rocker arm pivot axis and a groove on the bottom of which said rocker arm is supported.
