    Abstract: In a heat insulating engine of this invention, the piston head is made up of a retainer body, a heat insulating member mounted on the retainer body, and a thin ceramic member formed over the upper surface of the heat insulating member exposed to the burning gas and over the circumference of the former two members. The retainer body is mounted to a piston skirt through a heat insulating gasket. The cylinder is so constructed that the piston head does not contact the cylinder liner upper portion of the head-liner but can contact the cylinder liner lower portion. When the piston is situated close to the top dead center, the heat insulating structure of the combustion chamber prevents heat from being released from the piston head. When the piston is pushed down, the heat of the piston head is released through the cylinder liner lower portion, rapidly reducing the temperature in the combustion chamber, preventing fresh air taken in from thermally expanding and therefore preventing a reduction in the air intake efficiency.

    Abstract: An arrangement which includes a coned ring forms with the coned portion an interior space. The interior space decreases and increases its volume, when the coned portion of the ring is compressed and de-compressed. The coned ring has a radial outer portion and a radial inner portion. The radial inner portion forms a bore. The radial outer portion is provided with a seat face portion. The seat face portion contacts and bears a respective portion of a body, which may be a second coned ring, a thrust body or an outer ring. The arrangement is utilized to center a coned ring relative to a neighboring body or to provide and effectively seal a working chamber for the reception and expulsion of a fluid.

    Abstract: In an axial piston motor or pump the cylinder barrel is mounted on a medial shaft which has a shoulder which axially bears against the front end of the rotor barrel. The rear end of the medial shaft is radially borne in a housing portion. The front portion of the medial shaft is provided with a bearing member of an axial thrust bearing for support on a respective axial thrust bearing member in the housing. On the rear end of the rotary barrel an axially selfthrusting control body is provided to seal the flow of fluid to and from the cylinders of the rotary barrel. The control body presses against the rotary barrel, the rotary barrel presses against the bearing of the medial shaft and the thrust bearing member of the shaft bears on the thrust bearing member of the housing. As a result thereof the cylinders in the rotary barrel can be straight through bores. The manufacturing of the rotor barrel is thereby simplified and the flow acceleration losses of former sack-bare bore type cylinders are prevented.

    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. The speciality of the preferred embodiment of the invention is to provide an upper structure of an airborne craft with a plurality of propellers with substantially vertical axes to carry pivotable on the mentioned structure a body of the craft below the mentioned structure, while the body contains the cabine and the power plant as well as the fluid flow supply means, the upper structure is pivotable in a limited extend relative to the body and the fluid under pressure is transferred from the fluid flow supply means in the body to the upper structure and to the fluid motors which drive the propellers of the upper structure.
