    Abstract: A piston for a reciprocating internal combustion engine includes at least one pressure ring installed in an outer surface of the piston main body adjacent to the piston head. The pressure ring has a double-angle butt end construction comprising an outer circumferential surface slidably contacting the inner circumferential wall of the cylinder, a radially extending first butt flat end face, and a side wall facing the combustion chamber side, namely the high-pressure side, of the engine piston chamber. Only a corner portion formed on the combustion chamber side of the pressure ring by the outer circumferential surface, flat end face and side wall is partially cut away to form a notch which is contiguous to the outer circumferential surface, end face and side wall. The pressure ring further includes a radially extending second butt flat end face opposing the first flat end face, and a rib projecting circumferentially from the second flat end face only at a position corresponding to the notch, the rib having a shape which is complementary to that of the notch for being gas-tightly received by the notch when the pressure ring is installed in an outer circumferential groove of the piston main body.

    Abstract: A radial piston machine wherein fluid flows through the cylinders which are provided in a rotor, the disclosure provides a radial bearing in the middle between a plurality of at least two radial cylinder groups. Thereby the former bearings which were provided on the ends of the rotor can be reduced to smaller sizes to carry a lower radial load. The provision of the bearing in the middle of the rotor prevents the former miniturization of the control bodies on the ends of the rotor. The control bodies can now be radially enlarged and the restriction of the flow through quantities of fluid through the control bodies is overcome. The devices are now able to operate with a better efficiency and power. In order to obtain these features the medial radial bearing in the middle between the cylinder group must be of the specific structures of this patent application.

    Abstract: A piston assembly for an internal combustion engine is made up from a piston main body and a lubricant reservoir defining member. The piston main body has a cup-shaped structure including a crown portion and a hollow cylindrical wall portion joining thereto, two piston pin bosses being formed at opposite sides of the wall portion. The lubricant reservoir defining member is made from a shelf plate main body portion which provides a central lubricant reservoir and two openings on its opposite sides, and two major legs extending from the shelf plate main body portion and each formed with a hole surrounded by an annular portion. Each of the annular portions is engaged with an inner end portion of a corresponding one of the bosses and surrounds the piston pin hole thereof. Thus the lubricant reservoir defining member is securely mounted within the cup shaped piston main body by a reliable and simple construction, with the shelf plate portion generally parallel to and opposing the piston crown and thereby providing a central lubricant reservoir for aiding with the flow of cooling lubricant flowing in and out through the two openings to flow along the underneath of the piston crown.

    Abstract: A piston head structure in which a piston head made of a ceramic is firmly secured to the top portion of a metallic piston body through the medium of a metallic ring fitted to the lower part of the piston head. In assembling, the ceramic piston head to which the metallic ring is fitted beforehand is secured to the top portion of the piston body by a shrink fit or, alternatively, the assembly of the ceramic piston head and the metallic ring is inserted to the metallic material of the piston body during casting of the latter, and the cast piston body is then subjected to necessary mechanical processing. In this structure, the separation of the piston head from the piston body is prevented due to the close fit of the ceramic piston head and the metallic ring to the metallic piston body. Such a fit prevents separation even when the piston body is expanded due to the heat generated during operation of the engine. In addition, the ceramic piston head is protected by the metallic ring against any external force which acts to cause a cracking or breakage of the ceramic piston head, during the production of the piston.

    Abstract: In a vehicle or device a fluid motor is employed to drive rotary members, such as wheels, propellers, tracks. The motor is provided with an arrangement which includes a control means and an axially moveable member. By utilizing the control means for example by a flow of fluid, the axially moveable member is used to apply an action, which is not common to the usual operation of fluid motors. The arrangement may be used to arrest the rotor of the motor from rotation, when no pressure is in the driving fluid line. It may also be used to control the pitch of propellers with variable pitch arrangements. Also possible is to use the arrangement to automatically obtain an auto-rotation of rotor blades on vertical axes of vertically take off and landing vehicles, when the pressure in the fluid line to the motors for driving the motors drops below a predetermined minimum of pressure.

    Abstract: A method of manufacture of novel light-weight pistons of aluminum forgings with an integral iron insert ring by fusion welding is described. The aluminum piston forging is provided with a configuration adapted to receive the iron insert ring which may be coated to provide an inter-metallic joining alloy. The configured piston forging is placed in a mold, the ring is positioned in the configuration. The mold is rotated and molten alloy is introduced at an angle to deoxidize the forging and the ring, sweep the oxides to non-critical areas of the mold and to join the forging to the ring upon cooling to form a fusion weld.
