Abstract
A valve spring is provided. The valve spring may include a first turn. The first turn of the valve spring may be disposed at a first angular orientation. The valve spring may further include a second turn. The second turn may be disposed at a second angular orientation. The second angular orientation may be different from the first angular orientation.
Claims19
A valve spring disposed between valves and ports of an engine to control a movement of the valves of the engine, comprising:
- a first turn, wherein the first turn of the valve spring, the valve spring having an oval or elliptical cross-section, the oval or elliptical cross-section is disposed at a first angular orientation;
- and
- a second turn, wherein, the oval or elliptical cross-section of the second turn is disposed at a second angular orientation, wherein
- the second angular orientation is different from the first angular orientation.
A valve spring disposed between valves and ports of an engine to control a movement of the valves of the engine, the valve spring having an oval or elliptical cross-section, the oval or elliptical cross-section, comprising:
- a plurality of helical turns comprising a first turn and a second turn, wherein the oval or elliptical cross-section of the first turn is disposed at a first angular orientation and the oval or elliptical cross-section of the second turn is disposed at a second angular orientation, wherein
- the second angular orientation is different from the first angular orientation.
A method of forming valve spring disposed between valves and ports of an engine to control a movement of the valves of the engine, the valve spring having an oval or elliptical cross-section, the oval or elliptical cross-section, comprising:
- forming a first turn of the valve spring at a first angular orientation of the oval or elliptical cross-section;
- and
- forming a second turn of the valve spring at a second angular orientation of the oval or elliptical cross-section, the second angular orientation is different from the first angular orientation, wherein a part of the second turn is in contact with a part of the first turn.
