Title: Constant vacuum type carbureter
Inventor: YAMAZOE HIROSHI
IPC: F02M7/17
Filed: 1984-01-31
Abstract: PURPOSE:To make the full height of a constant vacuum type carbureter shorter by prolonging the friction piston guide part of the carbureter up to the upper part of a top cover. CONSTITUTION:The friction piston 10 of a constant vacuum type carbureter has venturi negative pressure caried from a hole 16 into a chamber 15 defined by a diaphragm 12 and is pushed up against the load of a spring 17 according to the negative pressure. The friction guide part of the piston 10 consists of two parts, namely, the main body part 3 and the internal projection 20A of a top cover 20. Any tendency of the negative pressure piston 10 that it is inclined at the high load time can be prevented by the engagement of the internal peripheral face of the piston with the projection 20A. As a result of the shortened guide part 3 which is the main body, the full height of the carbureter can be reduced.

Abstract: PROBLEM TO BE SOLVED: To enable constant current-voltage drop overcorrent control by a simple circuit, by making a switching power source have a switching circuit, a resonance circuit, a transformer, an output rectifying and filtering circuit, and a circuit for protection from overcurrent. SOLUTION: A pseudo sine wave current corresponding to the resonance frequency of a resonance circuit 2 flows to the resonance circuit 2 and the primary winding 31 of a transformer 3 by the switching operation of a switching circuit 1. At this time, induced voltage is generated in the secondary winding 32. This induced voltage is converted into DC by an output rectifying and filtering circuit 4 connected to the secondary winding 32 of the transformer 3, and then, outputted. A control circuit 6 increases the operation frequency in the case that the output voltage is high so that the output voltage Vo outputted from the output rectifying and filter circuit 4 may be constant, and controls a switching circuit 1 so as to lower the operation frequency in the case that the output voltage is low.  A circuit 5 for protection from an overcurrent detects the terminal voltage generated at a resonance inductor 22, and outputs it as an overcurrent detection signal S1.
