Abstract: A method produces piston-type accumulators, including an accumulator housing (10) and a separating piston, which can be displaced in a longitudinal direction inside the accumulator housing (10) and separates two working spaces located in the housing. One end face of the accumulator housing is sealed by cover part (20). The cover part (20) is fixed on one side (40) via the free longitudinal edge (32) of the accumulator housing (10). The edge is displaced towards the cover part (20), such that a functionally and positionally secure connection of a cover part is ensured within the housing of a piston-type accumulator without using standard threaded connections.

Abstract: An open port is provided on an inner peripheral surface of the cylinder bore of the reservoir apparatus and the port is exposed to the exterior of the reservoir apparatus. A hollow portion is formed concentrically with the port on a reservoir body. An annular thin portion is formed between the inner peripheral surface of the cylinder bore and the hollow portion surrounding the port in a radial direction. The thin portion is outwardly deflected and deformed by being pushed outwardly in a radial direction centering on the port in a range narrower than the inner diameter of the hollow portion. Thus, the opening of the port is outwardly sunk from the inner peripheral surface of the cylinder bore thereby to form a curved surface at a root portion of the thin portion on the inner peripheral surface of the cylinder bore.

Abstract translation: 在储存装置的气缸孔的内周面设置有开口，并且该端口暴露于储存装置的外部。 中空部分与贮存器主体上的端口同心地形成。 在气缸孔的内周面和径向包围端口的中空部之间形成环状的薄壁部。 通过在比中空部分的内径更窄的范围内以中心为中心的径向向外推动薄壁部分向外偏转和变形。 因此，端口的开口从缸孔的内周面向外沉没，从而在气缸孔的内周面上的薄壁部分的根部处形成弯曲表面。

Abstract: A hydraulic accumulator, especially a piston accumulator includes an accumulator housing (10) and a separating piston that can be longitudinally displaced in the accumulator housing (10) and divides two working chambers (12) inside the accumulator housing (10). The housing is sealed on each end by one cover part (16). At least one cover part is fixed, on one side (32) by a free longitudinal edge (34) of the accumulator housing (10). The edge is arranged against the cover part (16). By connecting the free longitudinal edge (34) of the accumulator housing (10) to the associated cover part (16) by a peripheral weld seam (46) for sealing at least one working chamber (12) from the environment in a gas-tight and/or fluid-tight manner, a reliable sealing is obtained by the weld seam (46). The weld seam also connects the free longitudinal edge (34) of the accumulator housing (10) to the associated cover part (16).

Abstract: A pressure container has a steel pipe and an end plate that is formed with a joint portion by allowing its tapered surface to touch a tapered surface of an opening end of the steel pipe so as to block the opening end. The steel pipe has a flange portion which can be cut at the opening end of the steel pipe, and the joint portion is allowed to touch the flange portion. The flange portion is pressed against the opening end along an axial direction so as to touch the end plate, and while the end plate is being pressed against the steel pipe along the axial direction, an electric current is applied so that welding is carried out.
