    Abstract: An internal combustion engine (10) comprising an engine frame (12) having a drive shaft (20) rotatably mounted therein and extending outwardly therefrom. A pair of cylinder sleeves (40, 40') are mounted on the engine frame (12) and have their inner ends positioned within the interior of the frame and their outer ends positioned outwardly thereof. A cylinder head (60, 60') is secured to the outer end of each of the sleeves and is separated thereby by means of a heat insulative gasket (70). Each of the cylinder heads (60, 60') has a dome-shaped chamber (62, 62') formed therein which is in communication with a source of combustible fuel. An air inlet conduit (94) is mounted on one end of the engine frame and is in communication with a source of air under pressure such as a blower, super-charger or the like. The air inlet conduit is in communication with an air passageway (100) formed in the engine frame (16) which is in communication with air inlet openings (52, 52') formed in the cylinder sleeves (40, 40'). The cylinder sleeves (40, 40') are provided with exhaust openings (54, 54') formed therein which communicate with an air exhaust passageway (102) formed in the engine frame (16). The exhaust passageway (102) is connected to exhaust conduit (106) or pipe extending from the engine frame (16). A piston (72, 72') is slidably mounted in each of the sleeves (40, 40') and has a dome-shaped head portion (76, 76') which is adapted to be received by the dome-shaped chamber (62, 62') in the cylinder head (60, 60') when the piston is in its top position. In the top position, the small "air space" (118) is present between the walls or sides (78, 78') of the piston head (76, 76') and the walls or sides of the sleeves (64, 64'). The "air space" (118) serves as a means for retarding the absorption of heat into the sides of the piston head (76, 76') and the sides of the cylinder sleeve (40, 40'). In the down position, the "air space" (118) also serves to spread the cooling air into a thin, wide sheet for more efficient cooling of the cylinder head (60, 60') and sleeves (40, 40'). Optional air deflecting fins (84, 86, 84', 86') may be employed on the piston head (76, 76'). The rings (82, 82') of the piston (72, 72') are conventionally lubricated and slide upon the interior wall (52, 52') of the cylinder sleeve (40, 40'). Each of the pistons (72, 72') has a roller (88, 88') mounted on the skin portion (74, 74') thereof which rolls upon a cam (32) mounted on a rotor plate (30) which is secured to the drive shaft (20) for rotation therewith. A return roller (92, 92') is also operatively mounted on the skin portion (74, 74') of the piston (72, 72') for engagement with a return cam (36) which is mounted on the drive shaft (30) for rotation therewith.

    Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber. A shaft seal which is disposed on an end portion of the main bearing, on a side opposite to the compression member, abuts on the rotary shaft.
