Abstract: A corrosion-resistant alloy tube is formed and bonded to a pre-machined steel alloy rod to form a riser tensioner cylinder rod. During assembly, an epoxy is injected into an annular space between the tube and rod and then cured. The bonded tube is ground to a desired surface finish prior to installation and utilizes a double seal arrangement that prevents external pressure or corrosive fluids from entering the cured epoxy in the annular space.

Abstract: There is provided a rocker arm of a kind in which even though the rocker arm is manufactured by the use of a press working technique the arm width can be minimized while the flat outer surface region of a required width is secured on an outer surface of the connecting wall, thereby contributing to reduction in size and weight of the rocker arm. This rocker arm 1 is capable of being driven by a cam 2 for selectively opening and closing a valve 3 of an internal combustion engine. This rocker arm 1 includes an arm body 4 prepared by bending a single plate material to represent a generally inverted U-shaped section including opposite side walls 5 and a connecting wall 6 bridging between the opposite side walls 5. A roller 10 engageable with the cam 2 is rotatably mounted on a portion of the arm body 4 generally intermediate of the length thereof. A valve drive element 8 is mounted on one end of the arm body 4 for driving the valve 4, while an end portion of the connecting wall 6 adjacent the other end of the arm body 4 is formed with an internally helically threaded hole 12 for threadingly receiving therein an externally helically threaded pivot member 7. An outer chamfered corner delimited between an outer surface of the connecting wall 6 and an outer surface of each of the opposite side walls and formed by bending is deformed to represent a plastically deformed portion 4a so formed by means of a plastic deformation technique that the outer chamfered corner represents a small radius of curvature R.

Abstract: The thickness in the width direction of a pair of side wall sections 4 is made as uniform as possible. In use, a load is applied to the pivot 3 from the side of the first and second connecting sections 5, 6 which connect the pair of side wall sections 4. A crimped section 13a is formed on the outer periphery at the opposite end surfaces of the pivot 3b, on the half on the side of the connecting sections 5, 6. Therefore, the outer peripheral surface of the opposite ends of the pivot 3b comes into contact with the inner peripheral surface of the through hole 11 on the load support side. Consequently, the load is sufficiently supported by the contact surface, and even after being used for a long time of period, lost motion is prevented from occurring on the support section at the opposite ends of the pivot 3 with respect to the pair of side wall section 4.

Abstract: One possible embodiment of the invention is essentially an apparatus and methodology for mounting a rocker arm assembly to a cylinder head of an internal combustion engine comprising of at least a unitary stanchion to which multiple rocker arms may be moveably connected. In least one embodiment, the unitary stanchion may comprise a base from which project multiple rows of pedestals. Two of more of these rows may be set in essentially parallel orientation, which further defines a primary space in which a portion of the rocker arm is located. The unitary stanchion may be secured to the cylinder head thorough multiple rows of fasteners. The footprint of the base of unitary stanchion could allow the unitary stanchion to possibly act as generally efficient external buttress for generally providing greater support across the top of the cylinder head.

Abstract: A rocker arm comprises an arm body, a shaft and a roller. The arm body formed substantially in a U-shape in section by effecting drawing on a metal plate, includes a connection wall connecting a pair of side walls, an aperture formed through the connection wall, and through-holes at positions where the pair of side walls are aligned with each other. A peripheral edge of the aperture is so formed as to be finished by inserting a first finishing die into the aperture from between the pair of side walls. The shaft is fitted in the pair of through-holes and extended between the pair of side walls. The roller is rotatably supported on the shaft.

Abstract: A sheet-metal rocker arm formed by the steps of punch-pressing a sheet of metal member to form a blank having a predetermined shape and a through-hole, of subjecting the blank to a bending process based on pressing to form a pair of substantially parallel side wall sections and a connection section for connecting the widthwise edges of the both side wall sections and to form at least one pair of circular holes in the both side wall sections at locations in alignment, of deforming the middle of the connection section in the thickness direction to form an engagement portion on one side of the connection section such that the engagement portion is recessed from the other portion of the connection section, and of forming on the other side of the connection section a bulge section, trapezoidal in cross section, which protrudes in an embanked-shape as the engagement portion is formed, whereby the widthwise edges of the middle of the bulge section corresponding to the top edge of the trapezoidal shape exist on the widthwise inside of the both widthwise edges of the engagement portion.

Abstract: A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. An elongate shaft extends through a transverse bore in the slider member and through a slotted passage in the slider member. In the follower body, the shaft is provided with bearings supporting first and second lateral roller followers on opposite sides of the body for variably engaging first and second preferably low-lift lateral cam lobes flanking the central cam lobe. A lost-motion spring urges the slider member into contact with the central lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the member slides within the follower body, allowing the lateral rollers to engage and follow the lateral cam lobes. Preferably, the latching mechanism is provided as a pre-assembled cartridge unit.
