Abstract
A valve train system that eliminates the inefficiencies of current spring biased systems. The system uses teeter beams that are manipulated by cams that are driven by cam shafts to control and operate the valve system more efficiently and dependably.
Claims3
A valve train system for internal combustion engines, said valve train system comprising in combination:
- i. a teeter beam having a near end and a distal end, said distal end of said teeter beam having a concavity in an upper surface thereof and said distal end having rotatably mounted thereon a first roller bearing;
- ii. said teeter beam being pivotally mounted at a center point of said teeter beam, on a rigidly affixed post, said pivotal mounting being tunable;
- iii. said near end comprising a grooved driver head, there being a second roller bearing rotatably mounted on said teeter beam at a point between said pivotal mount and said grooved driver head, and on a top surface of said teeter beam;
- iv. a grooved cylinder valve stem control interfacing with and integrated with said grooved driver head such that when the grooved driver head moves, the grooved cylinder valve stem controller moves therewith, said grooved cylinder valve stem controller having a retainer at a distal end of said grooved cylinder valve stem controller, said grooved cylinder valve stem controller being confined by a back stop retainer guide, said back stop retainer guide having a channel in a front surface thereof, a forward side of said grooved cylinder valve stem controller having a ridge thereon, said ridge slidably fitting into said channel;
- v. a bearing journal, said bearing journal containing a first cam gear mounted therein, said cam gear having a shaft, said shaft having mounted on a distal end, a primary cam anti-lobe, said primary cam anti-lobe interfacing with and periodically touching said first roller bearing;
- vi. at least two second cam gears having a shaft and mounted on said second cam gear shafts, two secondary cams, said secondary cams interfacing with and periodically touching said roller bearings, there being reciprocally, internally mounted in said grooved cylinder valve stem controllers, valve stems, said valve stems having a wide section mounted on and at a base of said valve stems, said valve stem having a retainer, said retainer being secured in place by a fastener, said cam gears configured to drive in the same rotational direction;
- vii. a spring mounted over said valve stem for providing spring tension on said valve stem.

A hydraulic lifter for a vehicle engine, said hydraulic lifter comprising:
- i. an upper canister, said upper canister having an upper end and a lower end, there being a snap ring groove located in an inside wall of said upper end;
- ii. a lower canister, said upper canister being moveable within a wall of said lower canister and there being a first opening through said wall of said lower canister;
- iii. a stem of a poppet valve being moveable through a
- iv. center point of said lower canister, said poppet valve stem extending through a center point in said upper canister, said upper canister being attached to said poppet valve stem by a fastening means;
- a spring, said spring being located in said lower canister, said spring surrounding said poppet valve stem;
- v. said lower canister having attached to an outside surface, a lifter guide;
- vi. said lower canister having attached to said outside surface, opposite said lifter guide, a cylinder valve controller;
- vii. said lifter guide having a second opening therethrough to pass hydraulic fluid into said lower canister, said second opening being aligned with said first opening;
- viii. said upper canister having a fluid exit port through a wall thereof.
