10 Claims.
This invention relates to lubrioators and more especially to devices of this character for supplying lubricant to the cylinders of internal combustion engines.
An object of this invention is an improved, inexpensive and efficient lubricator for furnishing lubricant to the cylinders of an internal combustion engine and so designed that the sup-- ply of lubricant to the cylinders increases with the speed of the engine.
Other objects, novel features and advantages of this invention will be apparent from the following specification and accompanying drawing, wherein:
Fig. 1 is a section on the line 11 of Fig. 2, and 1 Fig. 2 is a section on the line 2-2 of Fig. 1.
A. glass container 10 or the like is supported from a head 11 by means of a metal casing 12 which surrounds the container and is fastened to the head by means of screws 12 This metal casing is provided with a thumb screw 13 to the upper end of which is attached a spring 14 which extends into a recess in the bottom of the con-- tainer 10. -The casing 12 is provided with a reinforcing plate 15 to which are attached mounting bolts 16. The head 11 comprises a casting having a central portion 17 in which is provided a cylindrical passage 18. This passage is closed at its lower end by a plug 19 and is provided With a screw threaded cap 20. The plug 19 is provided with a small central passage 21 which is arranged directly above a cup 22 provided in an extension 23 from the head 11. A passage 24 is provided in the extension 23 and leads from the cup 22 to a chamber 25 in which is provided a. ball check valve 26. The chamber 25 communicates through a transparent conduit 27 with a port 28 adapted to receive a fitting 29. A regulating screw 30 extends across the passage 24.
The cap 20 carries a wire 31 which extends through the passage 21. A passage 32 formed in the head 11 communicates with a Venturi passage 33 formed in the plug 19. A tube 34 has one end communicating with the Venturi passage 33 and the other end extending nearly to the bottom of the container 10. The Venturi passage 33 is arranged radially with respect to the passage 21 and wire 31. The chamber 18 communicates with the interior of the container through passages 35 formed in the central portion 17 of the head 11. An air cleaner 36 is provided at the entrance to the passage 32.
This device is connected to the intake mani- 930, Serial No. 465,334
fold of an engine by means of a pipe (not shown) which is attached to the device by means of the fitting 29. By means of this connection vacuum conditions corresponding to the vacuum conditions existing in the intake manifold of the engine are produced within the various passages and chambers of the device, thereby causing a stream of air to flow into the device through the passage 32 and Venturi passage 33. The flow of air through the Venturi passage 33 draws lubricant from the container 10 through the tube 34, thereby producing a stream of atomized oil and air which is directed across the upper end of the passage 21. When the air velocity through the Venturi passage is high, as at low engine speeds when high vacuum is produced in the intake manifold, the air stream carries most of the atomized oil through the passages 35 and back into the container 10. A certain amount of the atomized oil is dropped into the well provided at the upper end of the passage 21 and this oil flows by capillary attraction down the wire 31 into the cup 22.
When the velocity of the air stream through the Venturi passage is low as at high engine speeds, a much larger amount of oil is collected in the well at the top of the passage 21 and flows along the wire'31 into the cup 22. The oil collecting in the cup 22 is drawn up through the passage 24 and is delivered through the conduit 27 to the pipe leading to the intake manifold of the engine. The proportion of oil deposited in the well 21 is greater at low velocity of air stream through the Venturi passage 31 than at high velocity of such stream. The velocity of this stream is directly proportional to the vacuum conditions existing in the intake manifold and as this vacuum is higher at low speeds than at high speeds, the amount of oil collecting in the cup 22 is greater at high engine speeds than at low engine speeds. Therefore, the engine receives a greater amount of lubricant at high speeds than at low speeds, which condition is extremely desirable and not present in cylinder lubricators now on the market.
