Electromagnetically-driven valve

Abstract

An electromagnetically-driven valve includes: intake valves that are arranged side by side; a disk that pivots using applied electromagnetic force to reciprocate the intake valves in a predetermined direction; and a connection member that connects the intake valves to each other. The connection member is provided with a needle bearing into which the pivot motion of the disk is input. The pivot motion of the disk causes a displacement between the needle bearing and the disk in a direction that intersects with the predetermined direction. An oil passage through which oil is supplied to the needle bearing is formed in the connection member.

1 . An electromagnetically-driven valve, comprising:
 a first valve and a second valve that are provided in an internal combustion engine, and that are arranged side by side;   a disk that pivots using applied electromagnetic force to reciprocate the first valve and the second valve in a predetermined direction; and   a connection member that includes an input portion into which pivot motion of the disk is input, and that connects the first valve with the second valve,   wherein the pivot motion of the disk causes a displacement between the input portion and the disk in a direction that intersects with the predetermined direction, and an oil passage is formed within the connection member and allows oil to be supplied to the input portion.   
   
   
       2 . The electromagnetically-driven valve according to  claim 1 , wherein the input portion is. a bearing that is arranged so as to contact the disk. 
   
   
       3 . The electromagnetically-driven valve according to  claim 2 , wherein the connection member includes an oil bath portion in which the oil that is supplied through the oil passage is stored and the bearing is disposed. 
   
   
       4 . The electromagnetically-driven valve according to  claim 2 , wherein:
 the bearing includes an outer race, and multiple rotating elements that are arranged inside of the outer race and that are aligned in a circumferential direction of the outer race; and   the outer race has an outer periphery that contacts the disk, an inner periphery that contacts the rotating elements, and a hole that extends from the outer periphery to the inner periphery.   
   
   
       5 . The electromagnetically-driven valve according to  claim 1 , wherein:
 the connection member includes a first fitting portion and a second fitting portion in which the first valve and the second valve are fitted, respectively; and   the oil passage is formed so as to communicate with at least one of the first fitting portion and the second fitting portion.   
   
   
       6 . The electromagnetically-driven valve according to  claim 1 , wherein both the first valve and the second valve are intake valves or exhaust valves of the internal combustion engine. 
   
   
       7 . The electromagnetically-driven valve according to  claim 1 , wherein the input portion is an oblong hole in which a pin provided in the disk is fitted in such a manner that the pin is allowed to reciprocate within the oblong hole. 
   
   
       8 . The electromagnetically-driven valve according to  claim 7 , wherein the oil passage opens at an inner wall of the oblong hole.
