UNITED STATES NICOLAI GRIBOJEDOFF, OF RASTATT, GERMANY.
AIR COMPRESSOR.
Application filed October 20, 1925. Serial No. 63,689.
To all whom, it may concern.
Be it known that I, NIcoLAI GnInoJnnoFr, formerly a citizen of Russia, residing at Rastatt, Baden, Germany, have invented certain new and useful Improvements in Air Compressors (for which I have filed an appli cation for patent in Germany March 30th, 1925), of which the following is a specifi cation.
My invention relates to a piston compressor having its cylinder rotating about its own axis, and a stationary annular valve onclosing the cylinder head, the ports in the annular valve operating with corresponding ports in the cylinder head to control the admission and the exhaust.
According to my invention the admission is effected through the space between the cylinder head and a cover plate mounted upon the annular valve, and the exhaust through hollow spaces in the annular valve. By these means not only is the construction considerably simplified but the cylinder head is eflfectively cooled without the use of special means for the purpose. The cylinder head may be formed as a blower, whereby a small super-pressure is produced in the admission chamber and thus admission to the cylinder is facilitated. vided in known manner with a jacket extending from the crank casing to a position above the cylinder head. In these circumstances the space between the cylinder and the jacket is according to my invention di-' vided by the annular valve into the admis-' sion chamber and a cooling chamber, and air may be drawn in by-suction through the cooling chamber, which is in communication with the admission chamber, thereby rendring a separate cooling apparatus unnecessary. The cylinder may, furthermore, be
provided in the cooling chamber with screw like vanes which act as a ventilator upon the air drawn in. a
The accompanying drawings illustrate an air compressor according to my invention, Figures 1 and .2 being lon itudmal sections of the whole engine on the 'nes 11 or 2-2 of Figure'3 respectively, and Figure 3 being a cross-section of the cylinder head, the annular valve and the jacket on the line 33 of Figures 1 and 2.
' The crank shaft (1 causes by means of the 4 connecting rod 6 the piston c to reciprocate verticall' in the compressor cylinder d which is mounted at the top and at the hot- The cylinder may be pro:
tom upon ball bearings, and at the same time causes the cylinder d to rotate about its axis by means of the bevel gear ef, the cylin der making one-quarter of a revolution at each single stroke of the piston. The cylinder is surrounded by a stationary jacket 2', which extends from the crank casing g to a position above the cylinder head h. The acket 2' carries a hollow annular valve 1: which is also stationary and surrounds the cylinder head It, and which has mounted upon it a two-part cover-plate Im.
The space between the cylinder (Z and its head It, on the one hand, and the jacket 2' and the cover-plate l-m, on the other hand, is divided by the annular valve it into an upper admission chamber 12 and a lower cooling chamber 0. These two chambers are in communication with each other by a tube 12, which at one end is connected by a flange to an opening g (Fig. 1) of the jacket 1', and at the other end has its nozzle 9 passing through an opening in the part m of the cover-plate into the admission chamber 11.
'lhe hollow space in the annular .valve ll:
is divided by transverse walls 'into two 0ppositely disposed admission chambers .9
(Figs. 1 and 3) and two opposite-exhaust chambers t (Figs. 2 and 3). The chambers s are open at the top, and thus communicate with the admission. chamber n, while the chambers t are in communication by ports u in the outer wall of the annular valve k, and by an annular groove 1) in the jacket 11 extending around the valve with the exhaust pipe w mounted upon the jacket.
The peripheral wall of the cylinder head It is provided with two pairs of super-posed ports a: which are diametrically opposite with respect to each other, (Figs. 2 and 3). The inner wall of the annular valve 70 is provided with four ports 3 spaced apart at y, with both the admission chambers s, and
during the same part of each upward movement of the piston through the same ports :0, and through both the other ports 3 with the exhaust chambers 25. Thus the piston a in its downward movement draws air into the cylinder d through the nozzle 1 the chamber a and the chambers s. This air is compressed during the first part of the upward movement, during which the cylinder is closed against all the chambers s and t, and is forced out during the second part of the upward movement through the chambers t, the ports a, the annular groove 12 and the pipe to.
Suction is not only eiiected directly through ports p of the tube 3) provided above the nozzle 1', but also through the crank casing 9, through the chamber 0 which is in communication with the crank casin b wa of the s )aces between the g J y y 1 cylinder (Z and the jacket 71, through the opening 9 in the jacket and through the tube p. The air drawn-in is forced outward in the chamber a by means of blades 2 cast on the cylinder head it, and the air is slightly pre-compressed in the chambers s. The cylinder (Z is provided in the chamber 0 with screw like blades a, which feed the air drawn in through the chamber in the manner of a ventilator.
