Abstract
A cam and follower apparatus adapted to translate the force of a piston to turn the shaft of an engine. The cam profile is made of three intersecting circles allowing for one follower to be near top dead center while another follower is near bottom dead center. The surface of the follower is a circle which shares the same center point and radius with the circles of the cam profile. The surface of the follower also closely intersects the axis of the follower preventing the follower from spinning like a roller follower. The follower can therefore spread the force from the piston to a wider area on the cam for longevity.
Claims6
An apparatus for translating reciprocal motion into rotational motion using a cam and follower comprising:
- a cam groove with an endless loop cam profile
- at least one follower
- wherein the cam groove with an endless loop cam profile is traced from a plurality of interconnecting circles forming an endless groove, wherein the surface of the at least one follower is a circle that shares the same axis and radius with the interconnecting circles forming the cam groove with an endless loop cam profile, wherein the surface of the at least one follower is located near its own axis and pivots back and forth following the adjacent surface of the cam groove with an endless loop cam profile, wherein the round face of the follower remains in constant contact with adjacent round faces of said cam groove with an endless loop cam profile to distribute forces involved from top dead center TDC and back.
A float-less valve assembly that can be screwed into an engine comprising:
- a) a valve
- b) a valve body
- c) a rocker
- d) a valve nut
- e) a spring
- f) a spring retainer mechanism
- g) a cam hook
- h) a valve cam
- Wherein the valve is inserted into the said valve body which can be screwed to the engine block or with the aid of the said valve nut, wherein the rocker is mounted on the valve body and being actuated by the valve cam, wherein the said cam hook is adapted for the said spring to sit on it and the said spring retainer mechanism to push against the valve stem and the base of the said hook to allow the head of the said cam hook to ride in a groove of the said valve cam, wherein as the said valve cam rotates with an engine rotating shaft, the lobes presses down on the rocker which presses down on the valve, wherein the groove on the said valve cam lifts up the said valve via said cam hook, wherein the said spring and retainer mechanism are used to keep the said valve cam in constant contact with the said rocker and said cam hook, wherein the said valve goes up and down with the said valve cam.
