Title: Variable valve timing controller
Inventor: NISHIMURA YUTAKA
IPC: F01L13/00
Filed: 1984-07-13
Abstract: PURPOSE:To precisely control the on-off timing of an intake/exhaust valve, getting extended life of the driver of said valve by setting a hydraulic cylinder at the fulcrum of the rocker arm of the intake/exhaust valve driver to allow the location of the supporting point to be variable. CONSTITUTION:Movement of a cam 22 rotating synchronized with a crank shaft is delivered through a rocker arm 20 to an intake valve 4. One end 21 of the rocker arm 20 is sustained by the top of the hydraulic piston 24 of a hydraulic unit 23. The rocker arm 20 is oscillated round a fulcrum of oscillation. A hydraulic unit 23 controls the oil volume, in hydraulic chambers 25 and 26 at both sides of the piston 24 by means of its hydraulic changeover unit 29. This configuration enables the hydraulic piston 24 to be displaced, the location of the fulcrum to vary and the valve lift property of the intake valve 4 to be altered. A hydraulic changeover unit 29 makes its change over function through controlling a solenoid valve 28 by a computer 16 despending upon the engine revolution and load data.

Abstract: PURPOSE:To eliminate the need for converting mechanical angles into electrical angles and thereby to simplify the entire process by a method wherein torque controlling is performed by means of an angle detector in a multiple-pole synchronous motor yielding voltages corresponding to the number of poles. CONSTITUTION:An angle detector 2 constituted of a 6-pole variable reluctance type rotating transducer is directly coupled with the rotor of a synchronous motor 1 of a 3-phase/6-pole structure type or the like.

The voltages thus obtained are supplied to a decision circuit 3 wherein the phasing is determined of the current in the stator winding, and the result is used, together with signals from a torque directing circuit 4 determining winding current absolute values, to supply winding currentsI1-I3 via a feeding circuit 5. Accordingly, the empolyment of the angle detector 2 eliminates the need for the conversion of mechanical angles into electrical angles and thereby greatly simplifies the controlling process.
