Filed: 1983-09-05
Abstract: PURPOSE:To calculate gear deflection by storing minimum and maximum values over the section of positions even if a timing pulse does not coincide with the position of the minimum value of deflection values. CONSTITUTION:If pulses P1-P5 are received during the rise of deflection values on the way of a cycle, the minimum value before the increment and a temporary maximum value are stored.

Title: Valve spring device for internal combustion engine
Inventor: HIRATA YUICHI
IPC: F01L1/14
Filed: 1993-06-07
Abstract: PURPOSE:To reduce the fuel consumption of an internal combustion engine by automatically adjusting the resilient expansion force of a valve spring fitted to a valve spindle for opening and closing the valve of the engine according to the rotating state thereof. CONSTITUTION:An upper spring seat 13 is detachably coupled to the upper surface of a fixed lower spring seat 10 via an auxiliary valve spring 17, and the lower end of a valve spring 5 is kept in contact with the seat 13. Also, both seats 10 and 13 are immersed in lubricating oil O. The upper seat 13 is fitted with a one-way valve 20 and a flow passage 24 is formed at the coupled section of both seats 10 and 13. At the time of the high speed operation of an engine, the viscous resistance of the lubricating oil O is high and the easy flow thereof through the passage 24 hardly takes place. Thus, the upper seat 13 remains at an upper position, and the displacement of the valve spring 5 can be made large. As a result, the resilient expansion force of the spring 5 increases. During the low speed operation of the engine, the upper seat 13 moves vertically with the inflow and outflow of the oil O from the valve 20 and the passage 24. The displacement of the spring 5 is thereby reduced and the resilient expansion force thereof drops.
