摘要： A lubricating oil pump comprising a distributor rotatably fitted in a cylinder chamber of a pump body, a plunger fitted to said distributor for the purpose of forming a pump chamber between said distributor and said plunger, said plunger being rotatable integrally with said distributor in rotational direction but being capable of performing relative movement in thrust direction in respect to said distributor, a cam and protuberance formed on one end face of said plunger, and a cam shaft comprising a cylindrical guide-column portion and control cam portion respectively engageable with said cam and protuberance for the purpose of controlling the stroke of said plunger, said lubricating oil pump thereby making it possible to manufacture at a low cost, being capable of maintaining high pumping efficiency and making it possible to control the delivery.

摘要： A lubricating oil pump comprising a plunger slidably and rotatably fitted in a cylinder chamber and having a worm wheel at one end and a lead portion at the other end thereof and arranged to form a pump chamber by means of a part of said cylinder chamber and said lead portion, said lubricating oil pump thereby providing comparatively large delivery in spite of the fact it can be manufactured at a low cost and is small in size.The lubricating oil pump further comprises an annular groove formed at a middle portion of the plunger and an eccentric cam, which is operable from outside, projecting into said annular groove and displaceable in thrust direction of the plunger so that the plunger stroke can be varied.
