MOTOR-VALVE.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed June 20, 1917. Serial No. 175,782.

To all whom it may concern:

Be it known that I, LOUIS STREBEL, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Motor- Valves, of which the following is a specification.

This invention relates essentially to a single valve with two passageways which is operated by means of a crank shaft connected to a piston adapted to reciprocate in a cylinder.

The object of the invention is to provide the valve with means for dividing it into a plurality of chambers or compartments, in staggered formation to control the intake and exhaust.

The invention is designed to provide a single intake in the cylinder for admitting the combustible, which also serves as an outlet for the products of combustion.

The valve being operated to rotate by means of the crank shaft, positively opens or closes the intake and exhaust at predetermined times, thus opening and closing the port in each cylinder at any speed of the crank shaft.

The invention is especially adapted to a four cycle explosive motor comprehending a seriesv of cylinders, the full mixture being admitted on one side of the valve, while the other side of the valve after the explosion will connect with the exhaust for conducting the products of combustion.

The novel features of the invention are more fully described in the following specification and claims, and illustrated in the accompanying drawings in which:

Figure 1 represents a vertical section of a 7 motor embodying this invention.

Fig. 2 is a horizontal longitudinal sectionof the valve and its. casing.

Fig. 3 is, a longitudinal section of the valve, showing the staggered formation of the chambers or compartments.

Fig. i is a cross section on line 4 4: of

Fig. 3.

Fig. 5 is a cross section on line 5 5 of Fig. 3.

Fig. 6 is a cross section of a valve and its casing on line 6 6 of Fig. 3, showing the in-' let from the carbureter. Fig. 7 is a cross section on line 7 7 of F .4

Fig. 8 is a cross section on line 8 8 of Fig. 3.

Fig. 9 is a diagram showing the successive strokes of the motor for one revolution of the valve.

In the drawings is shown an explosive engine or motor having a series of cylinders a coupled together, each provided with a piston 6 made to reciprocate in the cylinder by the explosion of a combustible as is Well known. The pistons are connected by means of rods 0 to the cranks (Z of a driving shaft 6 mounted to rotate in bearings f extending from the lower portions of the cylinders. A water jacket 9 is provided for cooling the cylinders.

Mounted on the cylinders is a cylindrical casing 71. having a bore 2' open at each end. A water jacket 2" is made to cool the easing. The casing is provided with a plurality of ports j forconnecting the interior of each cylinder at with the bore 2' of the casing 71, the function of which will be hereinafter described. i

In the center of the casing h is a semicircular opening or pocket 71/ partly encircling the valve k and serving as a heating chamber for the fuel and communicates with the carburetor at the top and at the bottom with the inlet ports of valve is.

A valve 71; is arranged in the bore of the casing, and it has packing rings m to prevent leakage of the fluid between the bore and the casing. This valve can be tubular as shown or it could be cylindrical with the intake and exhaust ports formed in the peripheryof the valve. A series of intake ports at and exhaust ports 0 are formed in the shell of the valve and coact at predetermined times with the ports 7' in the casing a communicating with the cylinders. These ports are nearly one quarter of the circumference of the valve.

A series of partitions in the valvelc divides it into chambers g and r in staggered formation, the former being adapted to lead off the products of combustion, while the latter constitutes the intake for the combustible mixture.

A cover t is bolted to each end of the casing it and to the rear one is fitted an exhaust 10 attached thereto, which connects with another sprocket wheel 11 fastened to the shaft through a chain 12. It will be seen that the sprocket wheel is twice the size of sprocket wheel 11. Therefore two revolutions of the crank shaft 0 will transmit one revolution. to the valve 70, thereby governing it to open or close the port in the cylinder at the proper time.

Intel-posed between the forward cover 23 and the sprocket wheel 10 is disposed a timer 13, which may be of any approved construction, and connected up in the usual way.

As indicated in Figs. 2 and 3, the chambers of the valve is form staggered passages in the valve to control the intake and exhaust of the four cylinders. The passages permit the first cylinder to explode the rombustible, the second to compress, the third to exhaust and the fourth to-intake the combustible mixture. Each cylinder has a single port 7' leading into the upper part of the cylinder and cooperating with the valve A, to at times intake the combustible, and at other times perform the function of exhausting the products of combustion after the ex plosion. The valve can be made to control any number of cylinders, and by its peculiar formation one port in each cylinder is sufficient for coaction with the valve, thus minimizing clogging of valves and subsequent fracture of the parts.

By referring to Fig. 3, it will be seen that the valve is is made hollow and composed of horizontal, Vertical and transverse partitions, forming chambersin a staggered for mation therein. These chambers communicate with ports j of each cylinder.

The central portion of the valve is has a circmnferential groove 15, which extends downward to about the center of the valve and has a horizontal and two segmental transverse partitions which separate the in let chambers r from the exhaust passage (1. The groove 15 is always in communication with the pocket or chamber h. At each side of said groove and staggered therewith are segmental openings 14 leading into the inlet chambers 1'.

At the left hand side of the groove 15, Fig. 3, it will be seen that the segmental opening 14- leads into the inlet chamber 1* and is sepa rated from the exhaust passage by a vertical partition 16, which extends to the center of the first and second intake and exhaust port and terminates With a transverse partition 17. This partition has two segmental openings 18 and 19 diametrically opposite each other.

From this transverse partition extends a horizontal partition 20 which terminates near the end of the valve and serves as a support for journal 2.

At the right hand side of the groove 15 is a transverse partition 25, the upper portion thereof terminates in the center of the third and fourth intake and exhaust ports with a transverse segmental partition 26. The lower portion extends to the transverse partitions 22. A horizontal partition 21 extends from the segmental opening 14 and terminates near the end of the valve with a transverse partition 22. This partition has two segmental openings 28 and 24 at the lower portion thereof, below the horizontal partition 21.

. It will now be seen that the combustible mixture enters the segmental groove from the carbureter, and passes to the left through the segmental opening 1 1 to the second intake port. Then through the segmental opening 18, under the horizontal partition 20 to the first intake port. At the right hand side, the mixture passes through the seg mental opening 14 above the horizontal par.- tition 9.1 to the third and fourth intake ports. The inlet passages are plainly indicated by single pointed arrows.

The exhaust passages are designated by double pointed arrows and are arranged as follows: Starting from the left hand side of Fig. 3, it will be seen, that the exhaust from the first cylinder is above the partition 20, thence downward to the second exhaust port,

through an opening 27 under the circumferential groove 15 and connects with the third exhaust port, then under the horizontal partition 21 with the fourth exhaust port, then out through the segmental open-. ings 23 and 24: into the exhaust pipe .9.

From the foregoing description it will be understood that the valve 7: during its ro- V tation is always in communication with the carbureter and at the proper time, the inlet ports are also registering with the ports in the cylinders. It will be seen, that by this construction, the heated mixture has but a short distance to travel and is delivered into the cylinders before being cooled off to any depreciable degree.

As indicated in Fig. 9, the four figures from top to bottom illustrate the four successive strokes of the motor. The position of the various pistons and their relation to each other when the front cylinder is about to fire is shown in the upper figure,- The pistons move downward during the explosion and intake strokes and they move upward during the compression and exhaust strokes. In this arrangement, the front cyl-' inder fires first, then the second cylinder, then the fourth cylinder, and lastly the third cylinder. The four operations of the cycle namely, suction, compression, explosion and exhaust are repeated in regular order in each of the four cylinders according to the firing order. When the first piston is at the top of its stroke with the fuel above it fully compressed and ready for ignition, the second piston is at the bottom of the suction stroke just at the beginning of its compression stroke and the valve is cooperating witli'the ports in both cylinders is closed. When the piston in the third cylinder starts moving up on its exhaust stroke, it will force the products of com bustion out of the cylinder through the passageway q of the valve 70. The piston in the fourth cylinder is then moving down ward and as the intake passageway r is adjacent to the port 7' it permits a charge of gas to be drawn into the cylinder from the carbureter.

It will be readily understood, that the valve with its two passageways could be utilized for governing the port of a hydraulic as well as pneumatic or any other fluid controlled engine.
