摘要： A variable compression ratio device includes a piston having a piston inner part and a piston outer part. The piston outer part integrally includes ear parts facing opposite ends of a piston pin and having long holes with longer diameters directed in an axial direction of a piston. A shaft portion connected to the opposite ends of the piston pin is slidably fitted in the long holes to allow an axial relative movement between the piston inner part and the piston outer part, while preventing relative rotation between the piston inner part and the piston outer part. Thus, the variable compression ratio device reliably prevents the relative rotation between the piston inner part and the piston outer part with a simple structure, and reduces weight of the piston.

摘要： A variable compression ratio device of an internal combustion engine includes a piston inner part connected to a connecting rod and a piston outer part fitted on an outer periphery of the piston inner part. The piston outer part is only slidably in an axial direction, and is movable between a low compression ratio position near the piston inner part and a high compression ratio position near the combustion chamber. A skirt part is slidable and is guided by an inner peripheral surface of a cylinder bore of an engine. The skirt part is integrally formed on the piston inner part. A peripheral wall of the piston outer part is terminated directly above the skirt part. Thus, switching of the position between the low compression ratio position and the high compression ratio position by an inertia force of the piston outer part is performed smoothly with a reduction in weight of the piston.

摘要： A liquid flow rate control valve is provided in which since a distributor (38) is rotated relative to a sleeve (37) by a first drive source (46) only through a predetermined angle, the total area of overlapping sections of a first opening (37a) of the sleeve (37) and the second opening (38c) of the distributor (38) changes, and a rotor (42) having a third opening (42c 42d) is rotated by a second drive source (47), it is possible to carry out PWM control of the liquid input from an input port (61e) and output it from an output port (61f). In this process, one end in an axis (L) direction of the rotor (42) disposed on an inside in a radial direction is coaxially connected to the second drive source (47), and one end in the axis (L) direction of the distributor (38) disposed on an outside in a radial direction is connected to the first drive source (46) via a gear train (66, 73, 70), and therefore, it is possible to individually rotate the distributor (38) and the rotor (42) while achieving a compact size by arranging the first and second drive sources (46, 47) in a concentrated manner at one end in the axis (L) direction of a liquid flow rate control valve (23).

摘要： An expander includes a piston formed from a top portion, a skirt portion, and a land portion. A hollow heat-insulating space is formed within the piston making heat transfer difficult. It is possible to maintain the land portion, which is in contact with the high temperature, high pressure steam in an expansion chamber, at a high temperature, thereby minimizing any decrease in the temperature of the high temperature, high pressure steam to prevent any decrease in the efficiency of the expander. Any increase in the temperature of the skirt portion, which is in sliding contact with a cylinder sleeve, is suppressed to ensure the performance of the lubrication. Piston rings are provided on the land portion to separate the high temperature, high pressure steam in the expansion chamber from the oil in the skirt portion for preventing the oil and the high temperature, high pressure steam from being mixed together.
