摘要： A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.

摘要： A method for sealing a liquid composite spring, includes the steps of: placing a sleeve-shaped outer wall around an upper portion of a core shaft, and forming an upper liquid chamber and a lower liquid chamber inside the outer wall; and arranging a sealing member at a bottom of the outer wall to seal the lower liquid chamber, wherein the sealing member is made of flexible material. The liquid composite spring is provided with the rigid outer wall and the flexible sealing member. The volume and shape of the lower liquid chamber can be changed through the flexible sealing member, so that the chamber is formed as a flexible chamber.

摘要： A bellows assembly for a downhole tool includes a first seal ring, a second seal ring, and a bellows positioned at least partially between the first and second seal rings. The first seal ring, the second seal ring, and the bellows are integral with one another such that the bellows assembly is monolithic. The bellows is configured to expand and retract. The bellows is annular and has a diameter that varies over a length of the bellows. A material composition of the bellows varies over the length of the bellows.

摘要： A flexible unit absorbing misalignment and transmitting torque from a driving shaft to a driven shaft is provided between a pair of flanges individually provided on each of the driving shaft side and the driven shaft side, both the driving shaft and the driven shaft being hollow. A communication passage letting hollow regions of the driving shaft and the driven shaft communicate with each other to form a circulation space for a cooling fluid is provided in the flexible unit. The flow of the cooling fluid cooling a driving source driving and rotating the driving shaft from the inside is created in the circulation space. A seal portion seals between the circulation space and an outside space to prevent leakage of the cooling fluid from the circulation space to the outside space.

摘要： Peripheral sections of two diaphragms are stacked on each other. The peripheral sections of the two diaphragms form an outer rim of a diaphragm damper. The outer rim is continuously sealed and joined by laser welding over the entire circumference of the outer rim. The thickness of the tip of the outer rim is set in correspondence with the spot diameter of a laser beam at the tip of the outer rim. A weld bead is formed by welding in the entire area of the tip of the outer rim.

摘要： A coupling joint includes: joint member which has gear teeth; a center tube which has gear teeth meshing with the gear teeth, and through which a rotational force is transmitted between the joint member via the gear teeth and the gear teeth; a seal member which blocks a lubricated space including a meshing portion of the gear teeth and the gear teeth from the outside between the joint member and the center tube; a lubricant which fills the lubricated space; and a pressure-equalizing member which is provided to face a part of the lubricated space, changes the volume of the lubricated space by deforming in accordance with the pressure of the outside, and thereby equalizes the pressure of the lubricant and the pressure of the outside.
