Title: Variable valve system for internal combustion engine
Inventor: USHIJIMA KENJI
IPC: F01M1/06
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To suppress the sudden movement of a rocker arm after the maximum lift where a load direction is reversed, by supplying lubricating oil to the clearance of a slide bearing via an oil groove before the maximum lift. SOLUTION: A rocker arm 28 is rotatably fitted externally to a control cam 26 fixed to the outer periphery of a control shaft 24. The rotation of a drive shaft 12 oscillates the arm 28 around the axis core of the cam 26 via an eccentric cam 20 and a ringlike link 22, to drive a suction valve 18 by an oscillation cam 16 via a rodlike link 30. An oil groove 46 for introducing lubricating oil is formed on the slide bearing portion 44 of the inner periphery of the arm 28 and the outer periphery of the cam 26. The groove 46 is set on the opposite side to the shaft 24 seeing from the axis core of the cam 26 in the maximum lift condition.

Filed: 1993-02-05
Abstract: PURPOSE:To provide a method for machining a metallic fine tube so that the reliability for the mixture of a dust or a metal impurity can be improved and the production cost can be controlled. CONSTITUTION:The internal part of a stainless fine tube 10 is filled with gaseous argon, the place to be bent of the fine tube 10 is heated to the state of a high temperature with an electric heaters 6-1 to 6-3 and 7, ad in this state, the fine tube is bent.
