Benefits of technology

"The present invention provides a connection device for connecting a rocker assembly, a valve assembly or an injection assembly in an internal combustion engine. The device allows for optimal distribution of lubricating oil even when made by a cold pressing method. The device is reliable, safe, and easy to make from readily available materials. It is designed to ensure even distribution of lubricating oil on contacting surfaces between the button and driving plate. The device includes a button with a recess for receiving an insert, and a slot extending from the lubricating hole to the outer periphery of the button."

Problems solved by technology

In prior solutions, the provision of the above mentioned slanted lubricating holes allows lubricating oil to be better distributed; however, this arrangement is not compatible with a cold pressing operation, and necessarily requires a further very expensive turning process.

Embodiment Construction

[0020]With reference to the number references of the above mentioned figures, the connection device for connecting a rocker assembly, a valve assembly or an injection assembly in an internal combustion engine according to the present invention comprises a button, generally indicated by the reference number 1, defining a substantially half-spherical recess 2, for engaging therein a spherical head 3 of an insert or screw 4, to be coupled to a rocker 5.

[0021]Said insert or screw 4 comprises a conventional lubricating duct 6 communicating with a further duct 7 defined in the rocker and leading to the recess where a hole 8 facing to a driving plate 9 associated with a spring 10 for coupling to a valve or an injection assembly is formed.

[0022]The main feature of the invention is that, on the button surface or face contacting the driving plate 9, a slot 20, extending from the hole 8 and leading to the button periphery, is formed.

[0023]The slot 10, which preferably radially extends, operate...

Abstract

A connection device for connecting rocker, valve or injection assemblies in internal combustion engines, comprises a button defining a recess for housing herein an insert coupled to a rocker assembly or the like, the recess including a lubricating hole and the button comprising a button face contacting a driving plate and including a slot extending radially between the lubricating hole and the outer periphery of the button.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a connection device for connecting rocker, valve or injection assemblies in internal combustion engines.[0002]As is known, in internal combustion engines, both of an Otto cycle type and a Diesel cycle type, the connection between the rocker assemblies and valves, or with the injection assembly, is typically made by a ball coupling allowing force to be transferred to a bottom body, consisting of the valve or injector device.[0003]The above ball coupling comprises a spherical head screw or insert, including a vertical element coupled to the rocker assembly, for engaging in a recess defined in a button element which, by engaging with a driving plate, allows force to be transferred to a component to be driven, usually comprising the valve or injection assembly, as is shown in FIGS. 1 and 2.[0004]Said button is held on the insert head portion by a resilient element or O-ring, preventing the button from disengaging from its...
