This rare?ed air will enter passages ‘I and 8 at different points about their walls due' to the spacing of openings l0 and II and thus 50 will mix with the carbureted mixture ?owing to the cylinders of the internal combustion engine. The operation of the engine will thus not be seriously affected by any excess unmixed air 55 ' 2,134,215 - 2 being introduced into one or more of the engine 2. In apparatus of the class described, the When the suction motor is employed to actu ate the compressing piston of an air compressor, the motor will be subject to intermittent opera combination of an intake manifold passage of an internal combustion engine, means forming a chamber surrounding said passage, said cham ber communicating with said passage by means tion, and the expansion chamber l5, besides caus ing a rare?cation of the air coming from the suc tion motor, will also “smooth out” or “dampen” a suction motor, a conduit for placing the motor in communication with the chamber, and an ex cylinders. the pulsations caused by the intermittent ?ow of 10 air from the suction motor to the manifold. In other words, if the expansion chamber were not present and conduit l2 directly connected to in let pipe 3 of the manifold, the intermittent charges of air resulting from the operation of the 15 suction motor during the compressor operation will cause the carbureted mixture to vary in-den sity each time air is introduced into the inlet pipe and, as a result, there would be uneven operation of restricted openings through the wall thereof, pansion chamber in constant communication with the chamber surrounding the manifold pas 1O sage, said expansion chamber having a volumetric capacity exceeding that of the ?rst mentioned chamber. 3. In apparatus of the class described, the combination of an intake manifold passage of 15 an internal combustion engine, means forming a chamber surrounding said passage, said cham ber communicating with said passage by means of a retsricted opening through the wall thereof, an expansion chamber in constant communica 20 20 “rolling” would be in timed relation with the‘op eration of the suction motor. ' By the use of the _ tion with one side of said chamber surrounding expansion chamber l5, chamber 9, and spaced the manifold passage and having a Volumetric openings communicating with passages ‘l and 8, capacity exceeding that of said chamber sur rounding the passage, a suction motor, and a the intermittent flow of air from the suction mo conduit for placing said motor in communication 25 25 tor during its operation is caused to have a fair ly even ?ow into the inlet pipe as expansion with the chamber surrounding the passage and chamber l5 and chamber 9 decrease the density on the side opposite‘that with which the expan sion chamber communicates. of the air, and passages l0 and II‘ tend to intro 4. In apparatus of the class described, the duce this rare?ed air into passages ‘I and 8 at of the engine ordinarily termed “rolling”. This 30 a uniform rate. ' It is not necessary for expansion chamber l5 to be placed upon the side of the spacer opposite that to which conduit I2 is connected. In Fig ure 4 I have shown the expansion chamber [5' as 35 being interposed between conduit l2’ and cham ber vcommunicating with said passage by means of a restricted opening through the wall thereof, an expansion chamber in constant communica 35 ber 9 of the spacer member. When thesuction motor is inoperative, this expansion chamber has tion with» said, chamber surrounding the mani fold passage and having a volumetric capacity the same degree of vacuum as the inlet pipe of the manifold. Whenthe suction motor is op passage, a suction motor, and a conduit connect 40. erated, the air therefrom'is ?rst introduced into expansion chamber l5’ and chamber 9 where its density is decreased prior to being evenly dis tributed into passages ‘I and 8 through openings I0 and II. Thus chamber IS’, in this position, 45 acts in the same manner as does chamber l5 of the structure shown in Figure 1, and the op eration of the engine is not affected while the suction motor is being operated. Being aware of the possibility of modi?cations 50 in the particular structure herein described with out departing from the fundamental principles of my invention, I do not intend that its scope be limited except as set forth by the appended claims. 55 combination of an intake manifold passage of 30 an internal combustion engine, means forming a chamber surrounding said passage, said cham ‘ Having fully described my invention, what I claim as new and desire to secure by Letters Pat ent of the United States is: 1.
