Embodiment Construction

[0033] Figure 1 to Figure 3 Shown is a cam follower roller device, generally designated by reference number 1 , which may for example be used in a fuel injection pump intended for a (not shown) internal combustion engine.

[0034] The device 1 includes: a tappet body 2; a pin 3 mounted on the tappet body 2; and a roller 4 mounted on the pin 3 in a rotationally movable manner. The pin 3 and the roller 4 are centered on the transverse axis X3, while the tappet body 2 is centered along the longitudinal axis X2. Axis X2 is perpendicular to axis X3.

[0035] In the following text, in order to facilitate the special identification of the device 1 of these and subsequent figures, the adjectives "longitudinal" and "transverse" and the adverbs "longitudinal" and "transverse" are defined with respect to the axes X2 and X3, respectively. horizontally". Thus, the longitudinal portion or portion is parallel to the axis X2, while the transverse portion or portion is perpendicular to sai...

Abstract

The invention relates to a cam follower roller device (1) having a tappet body (2) extending along a longitudinal axis (X2) and defining a tappet bore (8); a pin (3) centered on a transverse axis (X3)and including two opposite ends (14, 15) arranged in through-holes (12, 13) transversally facing one another on tappet body (2); and a roller (4) rotatably mounted on the pin (3) around the transverse axis (X3). The tappet body (2) is a machined metal tube or bar and is provided with a radial plate (20, 30) that is securely fixed within tappet bore (8), the radial plate (20, 30) being dedicated to support a longitudinally movable piston.

Description

technical field [0001] The present invention relates to a cam follower roller apparatus for automotive or industrial applications. [0002] An advantageous application of the invention is the use of the cam follower roller arrangement in fuel injection pumps intended for internal combustion engines, especially motor vehicles. Another advantageous application of the invention is the use of the device in a rocker system intended for controlling valves of an internal combustion piston engine. Background technique [0003] Such cam follower roller devices typically consist of an outer lifter body, a roller and a pin (made of bronze or steel). The rollers are rotatably mounted on the pins, and the roller assemblies are centered on the transverse axis, while the tappets extend along the longitudinal axis. The tappet is formed with a cylindrical body defining an inner volume in which the pin and the roller are arranged. [0004] For example in EP-A1-2 960 446, DE-A1-10 2014 2268...
