    摘要: A method for constructing and breaking in piston engines includes applying an integral phosphate layer to the interior cylinder wall prior to the insertion of the piston into a cylinder. The invention includes the improved engine so constructed. The phosphate layer decreases oil consumption and improves piston ring seating in such an engine. The phosphatizing solution includes a zinc or manganese salt in phosphoric acid at a pH between about 2.5 and 4.

    摘要: An improved aluminum-silicon hypereutectic alloy cylinder is provided by the following steps: machining the sliding surface of the cylinder to given dimensions; finishing the sliding surface to a degree that the primary crystal grains of silicon clearly appear; subjecting the finished surface to acid pickling to remove to a given depth the eutectic aluminum solid solution surrounding the primary crystal grains of silicon; subjecting the thus treated finished surface to a pickling-activating treatment which does not substantially corrode the primary crystals of silicon but retains them intact; electroplating a metal or alloy onto the sliding surface to give a layer flush with the top finished surfaces of the primary crystal grains of silicon, the type of metal or alloy electroplated depending on the contemplated member mating, to thereby improve the sliding performance of the sliding surface; whereby the top surfaces of the primary crystal grains of silicon and the electroplated metal surfaces provide the desired sliding surface in combination.

    摘要: A refrigerant compressor having a drive shaft rotatable to cause compression of a refrigerant gas, and a drive power transmission unit for transmitting a drive power from an external drive power source to the drive shaft, the drive power transmission unit having a pulley freely rotatably mounted around the drive shaft, a power transmitting element fixed to the drive shaft, and a shock absorbent rubber element arranged between the pulley and the power transmitting element for providing a positive engagement between the rubber element and the pulley, and between the rubber element and the power transmitting element. The shock absorbent rubber element absorbs a change in a load torque applied to the compressor before the torque change is transmitted to the external drive power source via the pulley, and disengages from at least one of the pulley and the power transmitting element when an excessive load torque is applied to the compressor to interrupt transmission of the excessive load torque from the compressor to the external drive power source.

    摘要: Sliding contact-making structures of an internal combustion engine, comprising (a) a cylinder unit having an inner plating coating containing a dispersoid substance; and (b) a piston provided with at least one piston ring, fitted into the inside of said cylinder unit in the axial direction so as to freely slide upon the inside surface thereof, wherein the thickness of the plating coating is tapered off in the axial direction at the edge of the plating coating on the side of a crankshaft, and/or the dispersoid content in said plating coating not in sliding contact with the piston ring, on the side of a crankshaft, is lower than that in sliding contact with the piston ring, thereby preventing peeling off of the plating coating and unnecessary abrasion of the piston as well as seizing, extending the life of the cylinder.
