A piston cross-member is in between the first cap and the second cap. A cover is formed with the piston cross-member and extends between the first cap and second cap.

Abstract: The invention relates to a linear drive device having a housing element in which at least one drivable actuating element is arranged, a guide unit which is coupled to the actuation element and moves relative to the housing element between two stroke end positions in linear direction, a stroke limiting device, by means of which a first stroke end position and a second stroke end position of the guide unit are adjustable, wherein the stroke limiting device has a first stop and a first counterstop for setting a limit of the first stroke end position and a second stop and a second counterstop for setting a first limit of the second stroke end position, wherein the stroke limiting device has a third stop which is adapted to set a second limit of the second stroke end position adjusted with the first counterstop.

Abstract: A piston assembly includes a piston with a first cap disposed on a first end of the piston and a second cap disposed on a second end of the piston. A piston cross-member is in between the first cap and the second cap. A first cover is affixed to a first side of the piston cross-member. A second cover is affixed to a second side of the piston cross-member. The second side of the piston cross-member is opposite the first side of the piston cross-member.

Abstract: A cylinder includes a cylinder body defining a cylinder bore. End caps close opposite ends of the cylinder body. A piston/rod assembly of the cylinder includes a piston portion and a rod portion. The piston portion is located in the cylinder bore and the rod portion extends outwardly of the cylinder body through at least one of the end caps and terminates at an end having a first interlocking member. The cylinder also includes an attachment member having opposite first and second ends. The first end of the attachment member has a second interlocking member for cooperating with the first interlocking member for attaching the attachment member to the end of the rod portion. The second end of the attachment member includes a mating feature for connecting the attachment member and thus, the rod portion to another part.

Abstract: A linear drive having a drive housing on which a carriage runs to an adjustable extent. The carriage covers over a channel-like housing recess, which is delimited by two mutually side wall. For limiting the stroke of the carriage a first abutment is provided on it within the housing recess, such first abutment cooperating is with a first counter abutment, that is so inserted from the outside into an opening in the one side that it extends into the housing recess.

Abstract: A dual end stop is provided for setting precise open and closed positions for the valve to which the pneumatic actuator is attached. In a preferred embodiment, a stop assembly housing contains two stop adjustment bolts as well as a cam that defines first and second stop surfaces. The stop assembly housing is preferably mounted to the actuator housing outside of the pressurized zone contained by the actuator housing. The stop bolts and associated threaded apertures are designed for minimum overhang of the stop bolts to provide more support. The stop assembly housing not only preferably houses the stop assembly components but also preferably serves as an adaptor plate for the various valves to which the actuator may be mounted.

Abstract: A steering cylinder for a tractor with internal, adjustable steering stops that do not occupy packaging space beyond the cylinder itself. End caps of the cylinder, between the piston rod and the cylinder, serve as the stops. The end caps are threadably mounted in the cylinder to enable adjustment. The stops can be rotated relative to the cylinder to thread the stops in or out, thereby changing the stroke of the steering cylinder. Once the stops are set to the desired location, they are held in place by a retainer that is bolted to the cylinder. The retainers can be selectively removed from the cylinder and then used as a wrench to rotate the stops to adjust the cylinder stroke. Adjustment is needed when different wheel and tire combinations are mounted on the tractor or when the tread width is changed. A travel limiter is mounted to the cylinder to prevent complete withdrawal of the stops and the resulting loss of hydraulic oil.

Abstract: A device for adjusting the central position of the pistons and the angular position of the pinion in a valve driving actuator comprises a tubular body in which are tightly movably arranged a first and second pistons having opposite racks, meshing with a central pinion which can turn through discrete angles. The main feature of the invention is that the inventive device further comprises limit means for limiting the stroke of the pistons toward the pinion, which means can be accessed from the outside of the tubular body.
