Description
Oct. 19, 1954 H. H. MAXIM HEAVY-DUTY SILENCER FOR RESTRICTED SPACES Filed Aug. 8, 1951 Inventor fro/nay Hirafn Hamilton Maxim Patented Oct. 19, 1954 HEAVY-DUTY SILENCER FOR RESTRICTED SPACES Hiram Hamilton Maxim Hartford, Conn., as-
signor to The Maxim Silencer Company, Hartford, Conn, a corporation of Connecticut Application August 8, 1951, Serial No. 240,819
3 Claims.
The present invention relates to silencers which by reason of the environment in which they are used must be confined to a relatively small space. In particular the invention relates to a silencer for use with a high powered V-type engine under severely restricted space conditions.
The invention will now be described with reference to the accompanying drawing, in which Fig. 1 is an end view of the silencer;
Fig. 2 is a section substantially on line 22 of Fig. 1, with some of the parts broken away to show their construction; and
Fig. 3 is a section on line 3-3 of Fig. 2.
The silencer comprises a cylindrical shell 50 of elliptical cross section closed at the ends by laminated, inwardly dished headers II and i2, and having sections [3, I 4, I5 and H; of laminating metal sleeves secured to the interior of the shell wall. The laminations are as usual both for strength and for preventing shell noise. Inside the shell transverse laminated partitions l1 and I8 divide the interior into a central inlet chamber I 9 and two outlet chambers and 2 i. A pair of inlet conduits 22 and 23 pass through the shell wall near its ends, through the outlet chambers 20 and 2| and partitions H and 3 respectively, and terminate with open ends within the inlet chamber at points about one-third of the length of the chamber away from the partition, with the open ends of the two inlet conduits in line with and facing each other. The two inlet conduits are connected in any suitable way to the two exhaust manifolds of a V-type engine. The pulses in the two manifolds not being in phase with each other, there will be low pressure in one of the inlet conduits at the same time that there is high pressure in the other. By having the conduits in line with and facing each other each will act as a sink or catcher for pulses discharged from the other, resulting in a substantial evening out of the gas pressure and in a reduction in the production of noise.
A pair of intermediate tubes 24 and 25 are secured in holes in the partition I! so that one open end of each tube is substantially flush with the partition and the other terminates just short of the center of chamber I9. A second pair of intermediate tubes 26 and 21 are similarly secured to the partition l8, so that the open ends of tubes 24 and 25, and the open ends of tubes 26 and 21, are in line with and face each other. Outlet conduits 28 and 29 pass through the shell wall and terminate with open ends near the center of their respective chambers 20 and 2!. The exhaust and inlet conduits have anti-resonating and bleed-off slots, and these conduits as well as the intermediate tubes have anti-resonating holes 3| arranged as described in the Bourne Patent 2,297,046, September 29, 1942.
The silencer described has many advantages. By using a single inlet chamber for the two manifolds of a V-type engine there will be a much greater evening out of gas pulses because the pulses in the two manifolds are in general not in phase with each other. By superposing the two sets in a single chamber a much more even pressure pattern will therefore result. There are furthermore a large number of possible paths open to the gas pulses and to the sound waves, so that both the pulses and the sound waves will be decreased greatly in intensity.
What I claim is:
1. A silencer having a cylindrical shell of elliptical cross-section closed at its ends, a pair of elliptical partitions secured transversely of the shell to form a single central inlet chamber and a pair of outlet chambers, a pair of tubes secured to each elliptical partition and spaced apart along its major axis, said tubes each opening through the partitions to the respective outlet chamber and extending into the inlet chamber substantially in line with the corresponding tubes extending inwardly from the other partition, an inlet conduit extending through each outlet chamber, centrally through the respective partition and into the inlet chamber and each having an open end in said chamber substantially in line with and facing the open end of the inlet conduit extending through the other outlet chamber, and an outlet conduit extending into each outlet chamber and having an open end therein.
2. A silencer comprising a shell closed at its ends, a pair of partitions secured transversely of the shell to form a single central inlet chamber and a pair of outlet chambers, a pair of inlet conduits extending through said outlet chambers and longitudinally of said inlet chamber in axial alignment, said inlet conduits opening toward each other in spaced relationship within the said inlet chamber, at least one pair of axially aligned tubes opening towards each other within said inlet chamber and extending through said partitions into the respective outlet chambers, and an outlet conduit opening into each of said outlet chambers.
3. A silencer comprising a shell closed at its ends, a pair of partitions secured transversely of the shell to form a single central inlet chamber and two outlet chambers, a pair of inlet conduits extending through said outlet chambers and substantially centrally and longitudinally of said inlet chamber to open towards each other in a substantial spaced relationship, two pairs of axially aligned tubes each pair of which opens towards each other in closely spaced relationship within said inlet chamber and extends through said partitions into the respective outlet chambers, the said pairs of tubes being located in diametrically opposed relationship with respect to said inlet conduits within said inlet chamber, and an outlet conduit opening into each of said outlet chambers.
