Abstract: A hydraulic pressure responsive accessory, such as a cavitation eliminator, for a hydraulic system and a replacement bladder assembly for the accessory. The accessory comprises a cartridge having an inlet for connection to a hydraulic system, and contains a gas filled flexible bladder which compresses and expands in response to pressure fluctuations in the system. This bladder is removably secured within the cartridge in a unique way which permits easy removal of a bladder in the field when worn and replacement of the bladder by that of the present replacement bladder assembly. Shield means are provided between the bladder and a grid overlying casing inlet openings to protect the bladder from impact damage, and means connected with the shield provide indication of excess bladder pressure or automatic release of excess pressure.

Abstract: A pulsation dampener is presented which includes a bladder assembly having a bladder which retains its surface area and therefore its capability to dampen pulsations during pulsation dampening. The bladder is axially and longitudinally symmetrical. The bladder assembly comprises a bladder double sealed at both longitudinal ends by the combination of a bladder anchor bolt and a pressed metal end plate to prevent leakage. Pulsation causes the bladder to assume a clover leaf cross sectional configuration, thereby maintaining the bladder surface area constant regardless of pulsation. One end of the housing is machined so that that end may be pressed to gradually reduce its diameter toward the end while causing the wall thickness of those portions of diminishing diameter to remain essentially identical to the thickness of the unmachined unpressed wall portions of the housing.
Abstract translation: 提供了一种脉动阻尼器,其包括具有气囊的气囊组件,其保持其表面积,并因此具有在脉动阻尼期间抑制脉动的能力。 膀胱轴向和纵向对称。 气囊组件包括通过气囊锚定螺栓和压制金属端板的组合在两个纵向端部双重密封的气囊,以防止泄漏。 脉动引起膀胱呈三叶草叶横截面构型,从而保持膀胱表面积恒定,而不管脉动。 壳体的一端被机加工成使得该端部可被按压以使其直径朝向端部逐渐减小,同时使得直径减小的那些部分的壁厚保持基本上与壳体未加工的未压壁部分的厚度相同。

Abstract: A separator is positioned to prevent pulsating fluid from mixing with working fluid or from contaminating dampening devices when dampening pulsations or eliminating cavitation. The separator includes a cylinder connected at one end to the source of pulsating fluid and the other to pressurized working fluid, such as is used in a pulsation dampners or cavitation eliminators, with a sliding elastomeric piston positioned in the cylinder therebetween. A diaphragm is formed at the center of the piston, The diaphragm is protected by perforated cages on either side thereof and acts to transfer high frequency vibrations directly across the piston. The piston is free to slide upwardly and downwardly within the cylinder to transfer lower frequency pulsations. A lubrication grease fitting is provided adjacent one end of the cylinder for lubricating the piston when it is positively located against one of two opposite interior stops within the cylinder.
