Abstract:
A shell member 10 constituting an accumulator 100 including a cover member 30, a shell member 10 having a cylindrical portion 11, an opening portion 13 formed at one end of the cylindrical portion 11 and welded to the cover member 30, and a closed portion 12 formed at another end of the cylindrical portion 11, and an accumulation part 70 accommodated in the shell member 10. The cylindrical portion 11 includes an upper end portion 11a, and a protruding portion 11c having the opening portion 13. The protruding portion 11c is thicker than the upper end portion 11a.
Abstract:
A hydraulic device includes a housing and a closure element arranged thereon. The closure element is connected to the housing by torsional welding.
Abstract:
The invention relates to an accumulator device, in particular in the form of a piston accumulator, having a dividing piston (22) which inside an accumulator housing (2) separates two media chambers (26, 28) from each other, and in particular separates a chamber (28) containing a working gas, such as nitrogen, from a chamber (26) containing a working fluid, such as hydraulic oil. The invention is characterized in that the dividing piston (22) is longitudinally movably guided in a guide device (24) and that the guide device (24) is arranged inside the accumulator housing (2) and extends at least partially along the longitudinal axis (10) thereof.
Abstract:
The invention relates to a hydraulic accumulator, in particular a low-pressure accumulator, comprising an accumulator housing (2) and a separating element arranged therein, in particular in the form of an accumulator bladder (22) separating two media chambers (3, 5). The hydraulic accumulator is characterized in that the accumulator housing (2) is formed of at least two shells (8, 10) welded together at their opposing end regions (24).
Abstract:
The present invention provides a Type 3 pressure vessel comprising a polar boss that is attached to a metallic liner and provides reinforced static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance of the liner orifice or neck region. In particular, the material of the polar boss has higher static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance relative to that of the liner material.
Abstract:
A pressure storage unit (2) for a camshaft, having an integrated controllable pressure storage device for supporting hydraulic engine components, which includes a housing (4) with a piston (14) mounted movably therein having a piston floor (18), and a spacer element (28) being provided on the piston floor (18).
Abstract:
A pressure vessel includes: an outer container unit having an inner space and first and second supporting portions; a lining container disposed inside the outer container unit and having an end portion that corresponds to the first supporting portion; an elastic diaphragm disposed in and dividing the inner space into air and water chambers, and having retaining and extending sectors that correspond in position to the end portion and the second supporting portion respectively; and a pressing member disposed in the air chamber and having first and second pressing segments that press tightly the retaining sector and the end portion against the first supporting portion and the extending sector on the second supporting portion respectively.
Abstract:
A volume accumulator (15), including a guide housing (33), a separating element (34) and a spring element (35). The separating element (34) is slidably mounted on an inner lateral face of the guide housing (33) and the spring element (35) is seated against the separating element (34) on one side and on the guide housing (33) on the other side. According to the invention, at least one indentation (47) is provided on the guide housing (33), with the indentation protruding into the guide housing (33). In the direction of the spring element (35), the indentation (47) has an open end against which the spring element (35) is seated.
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:
A hydraulic accumulator, particularly a piston-type accumulator, includes an accumulator housing (1) which defines a longitudinal axis (9), is provided with an opening that is concentric with the longitudinal axis (9) and is closed by means of a lid (11). The lid is secured in a form-fitting manner against axial forces by a wall portion (25) of the accumulator housing (1). The housing encompasses the lid and is radially deformed towards the inside. The hydraulic accumulator also includes at least one part (39) that is deformed perpendicular to the longitudinal axis (9) secure the lid (11) in a form-fitting manner against being twisted relative to the longitudinal axis (9).
