US 5,347,961 A · Engine valve actuating device

Abstract

An internal combustion engine valve actuating device located directly above each cylinder which has a co-axial venturi shaped duct (20) that is removably attached with threaded capscrews (24) and sealed with an o-ring (28). The interior of the duct contains a number of inwardly facing vanes (30) that hold an electromechanical valve actuator (48) complete with an engine intake valve (50). When a pulsed electrical signal is received by the actuator, opposed electromagnetic fields are developed reciprocating the valve. A fuel injection system introduces combustible fuel into the duct at the trailing edge of the vanes. The valve actuating device may also be applied to the exhaust system, less the fuel injection, and the valve actuator may be cooled by interconnecting cavities (60) within the vanes using engine coolant or oil.

Dependent claims

A reciprocating internal combustion engine valve actuating device disposed above each cylinder in an engine, the device comprising;

a cylindrical venturi duct having attaching means for securement to the engine, the duct is coaxial with a poppet valve;
a plurality of inwardly facing vanes within the venturi duct having fuel injection means therein, and
an electromechanical valve actuator centrally disposed within the duct supported by the vanes, said actuator having the poppet valve with a stem disposed within the valve actuator substantially parallel with the duct, the valve being reciprocated by electrical impulses creating an entrance from the duct to the engine cylinder for controlled induction.
