n. 25 1 2 9 7 M. ZACK SPOUT FOR DELIVERING GAS UNDER PRESSURE Filed on. 2. 1925 Patented Jan. 25, 1927.
UNITED STATES MICHAEL ZACK, OF
COLOGNE-ON-THE-RHINE, GERMANY.
SPOU'I! FOR DELIVERING GAS UNDER PRESSURE.
Application filed October 2, 1925, Serial No My invention relates to improvements in spouts for delivering gas under pressure, and the object of the improvements is to provide a spout which is not frozen or deformed by the reduction of the temperature caused by the expansion of the gas delivered from the spout. \Vith' this object in view my invention consists in so conducting the compressed gas and the expanded gas that there is an exchange. of heat between the compressed gas, which is at comparatively high temperature, and he expanded gas, the temperature of which has been reduced below freezing. Thereby a double efiect is produced: First the temperature of the compressed gas is reduced so that a large proportion of humidity contained in the compressed gas is deposited before the gas passes through the nozzle, and the said nozzle is not obstructed by freezing humidity,
second, the temperature of the expanded gas is increased by the heat transmitted thereto from the compressed gas, so that the deformation of the spout by the differenceof the temperatures is avoided.
For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing, in which the same reference characters have been used in all the views to indicate corresponding parts.- In said drawing, I
Fig. 1, is a sectional elevation showing the spout, and I Fig. 2, is an elevation in section taken on the line 22 of Fig. 1.
-In the example shown in the figure the spout consists of a cylindrical block 9 adapted to be secured to .or forming a part of a receptacle or pipe containing a gas; under pressure. The said block 9 is provided with an axial bore a opening into a chamber k. The said chamber communicates through segmental passages b with an annular chamher 7? provided between outer and inner cylindrical portions m and 0 provided at the delivery end of the block 9. The cylindrical portion m is formed with internal screw threads -0, and it has a cap p screwed thereto, the said cap being formed with an axial tubular portion at extending into the cylindrical portion 0. As appears from Fig. 1 the cylindrical portion 0 extends nearly to the bottom of the cap p, and the tubular member (1 extends nearly to the bottom of the cylindrical portion a. Thetubular member 11 is provlded. at its inner end with 60,129, and in Germany November 26, 1923.
an axial bore 7' opening into an axial bore bore 9 of the member (5. Within the bore (1 there is a valve 6 adapted to close the bore 7' and acted upon by a lever r at the other ends of which are springs disposed on either side of the lever tending to hold the valve e on its seat to close the aperture f.
The operation of the apparatus is as follows: For taking gas from the receptacle the 35 lever r is rocked away from the valve 0, which is therefore opened by the pressure of the fluid. The compressed gas flows through the axial bore a, the chamber h, the passages b, the annular passage 2', the annu- 7o lar passage t and the bore f. It appears therefore that the compressed and comparatively warm gas flows around the tubular memberd. Therefore there is an exchange of heat between the compressed gas fioW- ing through the passage t and the expanded and cooled gas flowing through the passage 9, and the compressed gas is cooled, while the expanded gas is warmed up to a certain extent. The humidity of the compressed so gas is therefore deposited in part within the passage t and in part within the passage 2', so that the gas flowing through the bore 7 is comparatively dry and obstruction of the said bore is avoided. On the other hand the an expanded or expanding gas is heated, so that further precipitation of the humidity is counteracted. Further, by the exchange of the heat of the compressed and expanded gasnon-uniform expansion of the metallic body of the spout is avoided, so that the passages are not obstructed by non-uniform expansion.
While in describing the invention reference has been made to a particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
I claim: i
1. In a nozzle for delivering compressed gas, an inlet, an outlet, a plurality of con- 5 centrically arranged chambers interposed between said inlet and said outlet, each of said chambers communicating at one end with one of said chambers, and at its opposite end with another of said chambers, I10 whereby the gas is caused to follow a tortuous course.
2. A device of the class described com prising in combination, a casing, a tubular member secured at one end within said casing and spaced therefrom to provide a chamber between the casing and said member, a diaphragm in said tubular member adjacent the said end, said diaphragm being provided with passages for conducting compressed gas into said chamber, and a delivery nozzle secured to said casing and extending within the tubular member, said nozzle being provided with an aperture at.
i that end of the nozzle which extends within said tubular member.
3. A device of the class described comprising in combination, a cylindrical casing, a tubular member secured at one end within said casing and concentrically spaced therefrom to provide an annular chamber, a diaphragm in said tubular member adjacent the said end, said diaphragm being provided with passages for conducting compressed gas into said annular chamber, a delivery nozzle secured to said casing and extending within said tubular member, said nozzle be- Ill}! provided with an aperture at that end of the nozzle which extends within said tubular member, a valve for said. aperture, and means for normally retaining said valve in closed position.
4. In a nozz e, for expanding compressed gas, an inlet for said nozzle, a valved out let for said nozzle, and a plurality of concentric annular chambers interposed between said inlet and outlet.
In testimony whereof I hereunto allix my signature.
