2 Claims.
This invention relates to an internal combustion engine and particularly to the block thereof.
It is aimed to provide a motor wherein the sticking of valves is eliminated and the construction of which is simpler and will produce a smoother running motor.
Another object is to provide a structure wherein a one-piece or equivalent block has but two valves, both positively driven from the crank shaft, and disposed on the opposite sides of the cylinders.
The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.
In said drawings:
Figure l is a plan view of my improved cylinder block;
Figure 2 is a fragmentary side elevation thereof;
Figure 3 is an end elevation of such block;
Figure 4 is a view primarily in horizontal section taken through the axes of the valve; and
Figure 5 is a vertical section taken on the line 5-5 of Figure 4. 7
Referring specifically to the drawings wherein like reference characters designate like or similar parts, the improved cylinder block is disclosed at w. For the most part this cylinder block may be cast in a single piece as shown. Any operative number of cylinders may be employed, for example six as shown at H. These cylinders preferably are provided with linings l2 of harder and better wear-resisting metal than the cylinder block itself, which linings are incorporated into the cylinder block when it is cast.
In accordance with my invention, I provide similar valves 13 and i l on opposite sides of the cylinders and within the cylinder block. These valves are of sleeve form as shown and are rotatable, and they preferabl operate in tubular linings iii of hardened or better wear-resisting metal than the casting of the cylinder block.
The valve l4- may be an intake valve adapted to receive the fuel charge through passages l5 in cylinder block and sleeves M, in communication with an intake manifold at E6, being suggested in dot-dash lines, detachably applicable to the cylinder block and in communication with a source of fuel supply. The valve M has suitable passages ll therein whereby it may register with the passages l5 and passages l8 feeding through the lining it and cylinder block to the associated cylinders.
Rotatable valve I3 is primarily an exhaust valve, and exhaust gases are adapted to pass from the cylinders through passages I!) in the cylinder block and sleeve l4 and through ports 20 into and from the exhaust valve through passages 2| to an exhaust manifold 22 of conventional form detachably bolted to the cylinder block.
In dotted lines, a conventional cylinder head 23 has been disclosed, such cylinder head being adapted to be bolted or otherwise fastened on the top of the cylinder block. The conventional pistons (not shown) operate in the cylinders II and are operatively connected to the crank shaft of the engine suggested at 24 and which is journaled longitudinally of the cylinder block. The crank case of the engine is suggested in dot-dash lines at 25 and is detachably connected to the cylinder block as by bolts or the like. A rotatable shaft 26, to operate a cam shaft, is journaled longitudinally of the cylinder block H).
A distributor is driven from the shaft 26, and the valves l3 and M are positively driven, all in timed sequence, lbeing previously set by key adjustment or means not necessary to show specifically. The valves under such circumstances cannot stick as do existing pocket valves. Such valves and the timing mechanism or distributor are driven from the crank shaft 24 of the engine, and to this end said shafts respectively have sprocket wheels 21, 28, and 29 keyed thereto, over which a sprocket chain 30 is disposed in order to drive the same.
Various changes may be resorted to provided they fall within the spiritand scope of the invention.
I claim as my invention:
1. A cylinder block for an internal combustion engine, said cylinder block having an upper surface across which a head is disposable and cylinders opening at said surface, valves journaled in the block, one on each side of the cylinders and below the upper extremities of the cylinders and surface of the block, the block having passages extending upwardly from the valves to the upper surface of the block, one of the valves having means of communication with the cylinders through one of said passages to serve as an intake valve, and the other valve having means of communication through the other of said passages with the cylinders to serve as an exhaust valve, the block also having passages leading to the valves from the sides of the block.
2. A cylinder block for an internal combustion engine, said cylinder block having an upper surface across which a head is disposable and cylinders opening at said surface, valves joumaled in the block, one on each side of the cylinders and below the upper extremities of the cylinders and surface of the :block, the block having passages extending upwardly from the valves to the upper 5 surface of the block, one of the valves having means of communication with the cylinders through one of said passages to serve as an intake valve, and the other valve having means of communication through the other of said passages with the cylinders to serve as an exhaust valve.
10 said gear wheel.
THEODOR GERDES.
