Abstract: A pressure accumulator includes an accumulator housing having first and second ports for receiving first and second pressure mediums, respectively, a movable separating element subdividing an interior of the accumulator housing into at least first and second working spaces, the first working space accommodating the first pressure medium and the second working space accommodating the second pressure medium, wherein the first port is in fluid communication with the first working space and the second port in fluid communication with the second working space. At least one sensor is operatively coupled to the first working space for measuring at least one characteristic of the first working space, and a gas generator is operative to generate a gas from ambient air, the gas generator including an outlet for outputting the generated gas, the outlet in fluid communication with the first port. A controller is operatively coupled to the at least one sensor and the gas generator, the controller configured to calculate an amount of gas in the first working space based on the at least one characteristic and upon the calculated amount of gas in the first working space being below a first threshold level, generate a command to introduce gas from the gas generator into the first working space.

Abstract: A cylinder assembly includes a cylinder, a nut and screw assembly, a thrust tube that extends axially from the nut and out the cylinder, a drive assembly mounted to the cylinder for rotating the screw to effect axial translation of the nut relative to the screw, thereby causing the thrust tube to axially extend or retract relative to the cylinder, and an anti-rotate feature for restricting rotation of the nut relative to the cylinder. The anti-rotate feature may include a guide member coupled to the nut and including at least one key on one of the guide member or the cylinder and at least one corresponding slot on the other of the guide member or the cylinder that engages on the key. The guide member may be allowed limited movement relative to the nut and/or the cylinder thereby preventing binding of the nut relative to the cylinder.

Abstract translation: 气缸组件包括气缸，螺母和螺杆组件，从螺母轴向延伸出气缸的推力管，安装到气缸的驱动组件，用于旋转螺杆以实现螺母相对于螺钉的轴向平移， 从而使推力管相对于气缸轴向延伸或缩回，以及用于限制螺母相对于气缸旋转的防旋转特征。 防旋转特征可以包括联接到螺母的引导构件，并且包括引导构件或气缸中的一个上的至少一个键以及接合在键上的引导构件或气缸中的另一个上的至少一个对应的狭槽 。 引导构件可以被允许相对于螺母和/或气缸的有限运动，从而防止螺母相对于气缸的结合。
