Abstract: A multistage piston actuator exerts a driving pressure against a spring pressure into pressure chambers of piston bodies, fitted into a cylinder body, to operate the push rod. Each piston body is combined with a partition fitted into the cylinder body. Each piston body includes a pressure receiving plate portion, and an axial rod and a slidable cylindrical guide portion extending concentrically in opposite directions, the axial rod having an axial air passage connected to the pressure chambers. Each partition includes a base plate portion having a through-hole which receives the axial rod of an adjacent piston body, a large-diameter outermost cylindrical portion fitted into the cylinder body, and a slidable cylindrical guide portion slidably fit-engaged with the slidable cylindrical guide portion of the piston body. The axial rods of each piston body are brought into contact to operate the push rod.

Abstract: A hydraulic cylinder has a cylinder housing in which is formed a pressure chamber variably bounded on one side by a piston of a piston subassembly that is longitudinally displaceable. A piston rod is rigidly connected with the piston, wherein the piston has an outer contour, which permits tilting of the piston subassembly in the cylinder housing, and a projection, which is at the pressure chamber side and on which a sealing element is centered and retained by a retaining ring. The sealing element has an encircling sealing lip that slidably and sealably bears against a sliding surface of the cylinder housing. The retaining ring is provided on the side thereof opposite from the sealing element with a stiffened prolongation.

Abstract: The invention relates to an elastic corrugated pipe single-acting cylinder-driven mechanical gripper with a series-connection plate spring framework. The mechanical gripper consists of a palm and two flexible fingers or a palm and three flexible fingers. The flexible fingers are identical in structure. Each flexible finger consists of an elastic corrugated pipe single-acting cylinder and a series-connection plate spring. Dimensions of all plate springs connected in series are optimally designed according to grasping objects. The mechanical gripper is driven by the elastic corrugated pipe single-acting cylinder to generate a grasping force. The mechanical gripper applies to the grasping of fragile, brittle objects or the grasping of objects varying with shapes and dimensions. When connected with a robot body, the mechanical gripper particularly applies to the production and logistic fields for grasping, sorting and packing of foods, agriculture products and light industrial products.

Abstract: A linear actuator includes a cylinder main body. With respect to the cylinder main body, a slide table is disposed for reciprocal displacement through a guide mechanism, which is disposed on the cylinder main body. A stopper mechanism having a stopper bolt is disposed on one end of the slide table centrally in a widthwise direction perpendicular to the longitudinal direction of the slide table. In addition, when the slide table is displaced along the cylinder main body, an end of the stopper bolt comes into abutment with an end of a cover of the guide mechanism, whereupon the slide table becomes engaged therewith and movement of the slide table is stopped.
