摘要： A hydraulic circuit includes a pump driven by a motor, an inverter for controlling the motor, and an accumulator. The inverter controls rotational speed of the motor such that the pump always discharges hydraulic fluid at a fixed flow rate, which is the sum of an average necessary flow rate and an adjustment flow rate. The accumulator operates, when the fixed flow rate and a necessary flow rate differ, in order to accumulate or discharge the hydraulic fluid to thereby secure the necessary flow rate.

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.

摘要： A mushroom-shaped shield body, that is, a shield body having a configuration consisting of a back surface tapered section having its diameter successively increased towards the inside of an accumulator and a stem portion, is disposed coaxially at the inside end portion of a liquid feed/discharge port of the accumulator, and an inner surface tapered section is formed along the circumference of the liquid feed/discharge port opposed to the back surface tapered section of the shield body to form an annular liquid flow path between said back surface tapered section and said inner surface tapered section so that the direction of the liquid flow passing through this annular flow path may be directed along the inner wall surface of the vessel of the accumulator, whereby a diaphragm disposed within the accumulator can be deformed so as to conform to the inner wall surface of the vessel and thus the volume efficiency of the accumulator can be enhanced.

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： 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.
