摘要： A piston configuration is provided, the configuration including a piston having a ring seat and a piston ring disposed within the ring seat. The piston ring is configured to form a sealing surface between a surface of the piston ring and a surface of the ring seat. The sealing surface is formed when a first pressure on a first side of the piston ring is greater than a second pressure on a second side of the piston ring. At least one fluid channel is configured to increase a surface area on the piston ring that is subject to the second pressure.

摘要： A stroke piston for a stroke piston compressor for generating compressed air for a vehicle, such as a commercial vehicle, includes a piston body with a piston floor, a piston skirt with piston skirt walls and pin hubs for receiving a piston pin, and at least two piston rings, which can be inserted into circumferential ring grooves of the piston body. Ridges of the piston body are provided between each two ring grooves and between the piston floor and the first ring groove arranged closest to the piston floor and the ring groove arranged closest to the piston skirt facing away from the other ring groove or grooves. At least one of the ridges is recessed at least over a partial section of its ridge height, which is measured parallel to the axis of the piston body, with at least one recess relative to the diameter of the piston body.

摘要： An improved piston ring for use as an intermediate piston ring in a piston assembly having three or more piston rings is provided. The piston ring includes a piston ring body which extends through an arcuate shape between opposite end faces. The piston ring body has at least one combustion gas guidance feature for allowing a greater flow of combustion gasses to pass the piston ring body when the piston is moving in one direction and for allowing a lesser flow of combustion gasses to pass the piston ring body when the piston is moving in an opposite direction. This allows for the ring gap at the outer diameter of the piston ring to be minimized without creating flutter in another piston ring above the intermediate piston ring during operation of an engine.

摘要： A piston device and its manufacturing method are disclosed. The piston device comprises a piston body having at least one annular groove on the side wall of the piston body, and at least one piston ring made of flexible material and mounted in the annular groove. The outer diameter of the piston ring mounted on in the annular groove is larger than the diameter of the piston body, so that the piston ring contacts with the inner wall but the piston body has no contact with the inner wall while the piston device moves reciprocally at the axial direction of the cylinder.

摘要： The present invention provides for a method of repairing a part, having a damaged portion that has deviated from an original configuration, by using a laser cladding process. The process comprises the steps of applying cladding material to the damaged portion, and irradiating the cladding material with the laser beam until such time as the cladding material substantially bonds with the part thereby forming a repaired area having a configuration substantially the same as the original configuration.
