LUBRICATING OIL FEEDER OF TWO CYCLE ENGINE MOUNTED ON GLIDING BOAT

摘要

PURPOSE:To improve throttle operating property, by leading water pressure inside a jet water stream pipe for obtaining thrust to a pressure chamber so as to displace a diaphragm, and also rotating a rotary shaft for adjusting a stroke so as to adjust automatically the stroke amount of a plunger in an oil feeder. CONSTITUTION:In a gliding boat 1, jet water stream is injected from a jet water stream pipe 2 backward by rotating a rotary blade 3 by a two cycle engine 4 so as to obtain thrust. And the plunger 8 of a lubricating oil pump 6 is put to reciprocating motion in an axial direction through engagement of a worm gear 19 driven by this engine 4 with a worm wheel 18, and sliding contact of a cam part 31 with the cam supporting part 32, so that the lubricating oil sucked into a pump chamber 9 is boosted to be discharged. In this occasion, pressure of the jet water stream is led from a pipe passage 54 into the pressure chamber 43 of a driving means 4C, and a rotary shaft 33 for adjusting a stroke is rotated through a diaphragm 42, a rod 46, and a lever 35, so that the engaging position of the cam supporting part 32 with the cam part 31, namely, the stroke of the plunger 8 is changed.
