摘要： A screw comprising a first member having a plurality of alternating first thread ridges and first thread grooves, a ridge width of the first thread ridges being larger than a groove width of the first thread grooves at a measurement diameter of the first member. The measurement diameter is determined by calculating a pitch diameter of a hypothetical member having a plurality of hypothetical thread grooves and hypothetical thread ridges, with the hypothetical thread grooves being identical to the first thread grooves, and with the hypothetical thread ridges and the hypothetical thread grooves having identical, but opposite, profiles, and with the measurement diameter being identical to the pitch diameter of the hypothetical member.

摘要： A thread joint to be subjected to the fluctuating load having a thread to be subjected to the tensile load from which a thread crest contact surface is cut off from the threads thereof in the direction of the tensile load, and the contact height of the same is lowered with respect to the other portion. Therefore, the maximum bending moment per unit area generated at the root of the threads is uniformed and the peak bending moment per unit area is reduced.

摘要： The hydropneumatic accumulator disclosed herein comprises a rigid upright vessel, the mouth of which is at the bottom, containing an inverted bag-like bladder. The mouths of the vessel and of the bladder are sealed to one another. The bladder extends upwardly within the vessel interior and divides the same into inner and outer compartments which respectively contain an incompressible liquid medium and a compressible gaseous medium. To protect the bladder from damage by uncontrolled flexure of its wall in response to variations in the relative pressures within the inner and outer compartments, an inverted conical shape-defining member projects down into the upper closed end of the bladder and a perforated rigid shell projects upwardly into the bottom of the bladder. In addition, vertically extending circumferentially spaced stiffening ribs are formed in the wall of the bladder to hold the bladder upright.

摘要： An accumulator (ACC) in which a container main body (1) and a closure member (5) are screw-joined together. A reverse-buttress internal thread or an internal thread having an included angle of 90 degrees is used as an internal thread of the screw-joined portion. The reverse-buttress internal thread is formed in such a way that the inclination angle (β) of a clearance flank of the buttress internal thread is the inclination angle (β) of a reverse pressure flank (20A) receiving a load, the inclination angle (θ) of a pressure flank is the inclination angle (θ) of a reverse clearance flank (2B). The internal thread having an included angle of 90 degrees is formed in such a way that inclination angles (α),(γ) of both flanks are equal and the included angle (δ) is about 90 degrees.

摘要： An O-ring mounting groove has a bottom surface, which is formed as a recess whose section has an arc-like configuration so as to prevent concentration of stress. A backup ring, which is to be fitted into this O-ring mounting groove, has a lower surface whose configuration is in conformity with the bottom surface of the O-ring mounting groove, so that, when an axial force is applied to the backup ring, it is pushed outwardly.
