Description

Jan. .12, 1960 J, KAPlTULA 2,920,929
CYLINDER HEAD Filed Sept. 13, 1957 'any United States Patent O CYLINDER HEAD John Kapitula, Jersey City, NJ.
Application September 13, 1957, Serlal No. 683,799 1 claim. (cl. aos-'2) This invention relates to cylinder heads, and is preferably, but not necessarily, used with one of the types of piston disclosed in my pending application, Serial No. 672,182, led luly 16, 1957 and entitled Pistons.
An object of the invention is to increase the pressure and therefore the velocity of a piston operating in a cylinder having a head constructed as herein shown, described and claimed, whereby a desired pressure is obtained with a smaller piston, thus diminishing the weight of the engine.
The drawings illustrate the invention, and in these:
Fig. l is a side elevation of a cylinder head in accordance with my invention, and
Fig. 2 is a sectional view taken in line 2-2 of Fig. 1.
Referring to the drawings for a more detailed description thereof, the cylinder head shown is in two sections,
l 3 and 5, of which section 5 may be used alone or in combination with section 3. Section 3, as shown, is threadedly connected to section 5, as indicated at 6. Section 3 has a cavity therethrough, in the form of a double cone, with a throat 7 between the conical 4sections 8 and 9. Section has a funnel-shaped blind cavity comprising a conical section 10, which is continuous with a constricted cylindrical section 11, the latter terminating in point 12.
The motive medium, as steam, water, gas, enters section 8 and is thereby funneled into the throat 7, and then into sections 9, 10 and 11 to the point 12. The motive medium is speeded in passing through the mentioned venturi section and builds up a pressure beyond it. There is thus produced a reservoir of the motive medium at high pressure which, on escaping into the cylinder as the pressure in the latter is falling, puts a boosting pressure on the piston to increase its velocity. When the cylinder head is used with the piston shown in the above idented application the desired etect is enhanced by obtaining what I call a point-to-point or a line action of pressure.
It is to be understood that the motive medium, as steam or gas, under pressure, enters the cylinder between the pistons and the cylinder head, in the usual manner, and being under pressure, is forced into the described cavity of the head.
Wha-t is claimed is:
A cylinder head having an internal, axially disposed cavity adapted to receive a motive medium, the cavity comprising a venturi section extending rearwardly from its face and in the form of a pair of opposed forward and rearward cones with a throat between their apexes, and a conical section in base-to-base relation with the rearward cone of the venturi section.
