Title: Valve system of internal combustion engine
Inventor: KONNO TSUNEO
IPC: F01L13/00
Filed: 1989-02-25
Abstract: PURPOSE:To make the construction of an valve operating device simple and decrease the number of parts used by installing a control valve which receives supercharging pressure from a supercharger and controls the pressure oil feed and discharge to a hydraulic valve operating condition changing mechanism. CONSTITUTION:In an engine 1 provided with a supercharger 40, the diaphragm chamber of a control valve 43 is communicated with an intake passage 33 on the downstream side from a compressor 41 through a control passage 49. A control valve 43 is operated through the supercharging force generated by the compressor 41 to feed the pressure oil from an oil pump 53 to the pressure oil chamber of a hydraulic valve operating condition change mechanism. As a result, a suction and exhaust valve is opened and closed by a cam for the action of the supercharger 40 and the engine 1 is operated with the suction and exhaust characteristics confirming to the action of the supercharger 40. Since there is no need of detecting electrically the supercharging condition of the supercharger 40, it is possible to provide a simple structure by reducing the number of parts used with low cost and simple maintenance.

Abstract: PURPOSE:To prevent erroneous operation due to mechanical shock, by supplying the output of the time constant circuit of a vibration sensor to an amplifying circuit and stopping the alarm sound of a state circuit, which was initially reset by the operation of an alarm switch, by said output. CONSTITUTION:When an alarm switch S is closed at a set time, a transistor T2 initially resets a state circuit by transistors T2, T3 because the time constants of a resistor R3 and a condenser C2 are set small and a gate circuit G is opened to generate alarm sound while a piezoelectric element P responds to generate a signal. However, because the time constants of a resistor R2 anda condenser C1 are set largely, the threshold level of the base of the transistor T1 is not exceeded and the transistor T1 is not turned ON. By th is method, erroneous operation, such that alarm sound is stopped by mechanical shock accompanied with closing of the switch S, can be prevented.
