Md., by Esther C. Goddard, executrix, Worcester, Mass., assignor of one-half to The Daniel .and Florence Guggenheim Foundation, New York, N. Y., a corporation of New York `Application November 1, 1947, Serial No. 783,595

3 Claims. `(Cl. 60-46) l.

This invention relates to combustion apparatus in which intermittent feed is provided for two combustion liquids, as gasoline and liquid oxygen and is a continuation in part of prior Goddard application Serial No, 522,101 led February 12, 1944, and relates to divisional subject matter In such apparatus, as shown for example in the prior Goddard Patent #2,409,036, successive small amounts of two different combustion liquids are fed to a combustion chamber and are successively detonated. This produces a rapid succession of relatively small explosions which simulate continuous combustion but with avoidance of dangerous and violent explosions.

It is the general object of the present invention to provide improved and simplified mechanism for effecting such intermittent feed and for alternately introducing portions of a neutral liquid. A further object is to provide a mixing chamber in which the combustion liquidsmay be effectively intermingled in small quantities and between interposed portions of a neutral liquid.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims. v

A preferred form of the invention is shown in the drawing, in which:

Fig. 1 is a sectional side elevation showing the improved construction but with the motor drive shaft broken away for clearness;

Fig. 2 is a somewhat diagrammatic sectional plan view of a rotating valve and associated parts;

Fig. 3 is a perspective view of said rotating valve and its supporting bearings; and

Fig. 4 is a detail sectional view to be described.

Referring to Figs. 1 to 3, the upper portion of a combustion chamber C is provided with a tubular extension I0, to the upper end of which supply pipes I2, I4 and I6 are connected. The pipe I2 may supply gasoline, the pipe I4 may supply liquid oxygen, and the pipe I6 may supply water.

The inner ends of the pipes I2, I4 and I 5 `are closed by a conical partition having an upper port opening out of the pipe I2, an intermediate port 26 opening out of the pipe I4, and a lower port 21 opening out of the pipe I6.

A conical valve member 30 is supported in upper and lower bearings 3| and 32 and rotates within the conical partition 20. 'I'he lower bearing 32 is preferably supported on a plurality of radial arms 33 (Fig. 3).

The valve member 30 is hollow and is provided with an upper annular series of ports 35, an

intermediate series 36 and a lower series 31. The ports and36 are preferably disposed in diametrically opposite aligned pairs as shown in Fig. 3, and the ports 31 are diametrically disposed and alternate with the pairs of ports 35 and 36. The valve member 30 may be rotated at relatively high speed in any convenient manner as by a motor M.

The partition ports 25, 26 and 21 and the valve ports 35, 3 6 and 31 are so disposed and related that, as the valve member 30 rotates, the partltion ports 25 and 26 for gasoline and liquid oxygen willbe simultaneously uncovered, while at the same time the port 21 for water will be closed.

Each such injection of portions of the two combustion liquids is immediately followed by the injection of a portion of water or other neutral liquid through the partition port 21 and one of the valve ports 31, the port 21 being uncovered as the ports 25 and 26 are closed by further rotation of the valve member 30. A portion of water is thus interposed between each two successive charges of the combustion liquids.

vThe spaces containing combustion liquids are indicated by horizontal lining at A in Fig. l and the spaces containing the neutral liquid are indicated by vertical lining at B.

Successive charges of combustion liquids are thus separated from each other by interposed portions of neutral liquid as the charges pass downward along the tubular extension I0 to the combustion chamber C, where they are then ignited or detonated by the residual heat of the combustion chamber.

AIf the ports in the rotating valve member 30a -bustion chamber comprising a, tubular premlxing extension `of said combustion chamber at the `lar extension, a rotated hollow valve member said valve member to uncover the openings of said third row alternately with the openings of said first two rows, thereby admitting a small portion of said neutral liquid to said premixing extension between each two successive admissions of combustion liquids from said first two rows of valve openings.

2. Combustion apparatus comprising a xed combustion chamber, means to supply combustible,.`oxidizing and inert liquids thereto, a hollow conicalvalve member controlling the ow of all of said liquids, and means to continuously rotate said valve to periodically interrupt the flow of the ycombustible and oxidizing liquids and to simultaneously provide flow of the inert liquid through said valve.

3. Combustion apparatus comprising a, xed combustion chamber, means to supply combustible, oxidizing and inert liquids thereto, and a hollow conical valve member controlling the ow of all of said liquids, and said conical valve member having ports with inwardly offset edge portions, whereby the iiow of liquids through said ports elfects rotation of said valve member to periodically interrupt the flow of the combustible and oxidizing liquids and to simultaneously provide flow of the inert liquid,
