UNITE sr OTTO HAJEK, OF VIENNA, AUSTRIA, ASSIGNOR TO THE FIRM OF ALEX. FRIEDMANN, OF VIENNA, AUSTRIA.

OIL-DISTRIBUTING DEVICE.

Application filed May 25,

To all whom it may concern:

Be it known that I, OTTO HAJEK, engineer, a citizen of the Republic of Austria, residing at Vienna, in the county of Lower Austria and State of Austria, have invented certain new and useful Improve ments in Oil-Distributing Devices, of which the following is a specification.

This invention relates to oil distribution devices provided with a plurality of oil pumps, having plungers that are self regulating by virtue of a reciprocating and an oscillating motion about their axes. This invention consists mainly in providing novel and improved means for imparting reciprocating and oscillating motion to the plungers whereby the movement of a plurality of plungers is brought about in a more simple and effective manner than in arrangements hitherto known, which is due to the fact that a side shaft which is in parallel to the plungers is subjected to a reciprocating and s1- multaneously to a rocking movement about its axis. This side shaft transmits its movement to the plungers by means of a disk or cam and by means of eccentric trunnions integral with or fixed on the plunger heads.

In the accompanying drawings Figs. 1 and 2 show cross sections through the device at right angles to each other. Fig. 3 shows the disk transmitting the movement of the side shaft to the plungers.

In the drawings the reference numeral 1 indicates the side shaft, which is arranged in parallel to the plungers 2 of the pump, the said shaft being subjected to a reciproeating and at the same time to an oscillating movement around its axis by th driving shaft 3 through the medium of the eccentric pin 4. The side shaft 1 carries the disc 5, fixed in a position perpendicular to its axis, and having recesses in which the journals or trunnions 9 may enter; the said trunnions are arranged eccentrically to the plungers and are provided with collars 8. The disc 5 can be slidably arranged on the sid shaft 1 and a dead stroke determined by the position of th nuts 13 may be provided for; the stroke of all the plungers of the pump will be reduced by the amount of this dead stroke and the head or output of the pumps will diminish accordingly.

By means of the duct or channel 11 provided in the plungers 2 the oil at the suction stroke will be conveyed from the oil cham- 1921. Serial No. 472,611.

her 6 into the pump cylinder, while at the pressure stroke it will be conveyed from the cylinder into the pressure duct 12. After having removed the eccentric pin t the side shaft 1. and the plungers of the pumps may be removed simultaneously.

By means of a driving and regulating shaft, subjected to a reciprocating and simultaneously to an oscillating movement about its axis and being arranged with its axis in parallel to the plungers of the pumps it is possible to obtain a reciprocating and self regulating movement of the plungers in a manner which is more simple and effective than any means hitherto devised to bring about the same result, without need to resort to swaying disks or to intermediate shafts.

I claim 1. In an oil distributing device in combi nation, a plurality of oil pumps, plungers for said pumps, a shaft parallel to said plungers, means for reciprocating and oscillating said shaft about its center and means including a common actuating member operable by said shaft for transmitting reciprocating and oscillating movements from said shaft to said plungers.

2. In an oil distributing device in combination, a plurality of oil pumps, plungers for said pumps, a shaft parallel to said plungers, means for reciprocating and oscillating said shaft about its center and means for transmitting said reciprocating and oscillating movement to said plungers, said last mentioned means comprising trunnions mounted eccentrically on said plungers and a disk on said shaft engaging said trunnions.

3. In an oil distributing device in combination, a plurality of oil pumps, plungers for said oil pumps, a shaft parallel to said plungers, means for reciprocating and oscillating said shaft and means for transmitting said reciprocating and oscillating movement to said plungers, said last mentioned means comprising eccentric trunnions on said plungers and a disk slidably mounted on but reciprocated by and rotatable with said shaft and engaging said trunnions.

4. In an oil pump, in combination, a group of pump plungers having eccentric trunnions thereon, a shaft having its axis arranged longitudinally with respect to the axes of said plungers, means for reciprocating and oscillating said shaft, and means for transmitting reciprocatory and oscillatory movements from said shaft to said plungers, comprising an actuatlng member which is reciprocated and oscillated by said shaft andv barrel, a plunger in said barrel, a shaft par-' allel to said plunger, means for imparting a. 10 reciprocating and oscillating motion to said shaft, an eccentric trunnion on said plunger, a disk on said shaft engaging said trunnion, operative by said shaft to reciprocate and oscillate said plunger.

In testimony whereof I aflix my signature 15 in the presence of two Witnesses.
