摘要： 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.

摘要： A hydraulic cylinder in which a recess (21) is formed in a piston rod (3) side end surface (20) of a piston (4) so that the recess (21) serves as an axial fitting portion, and an end of the piston rod (3) is fitted into the recess (21) of the piston (4) to ensure the coaxial relationship between the piston rod (3) and the piston (4). Axial threaded holes (24) are formed in an end surface (23) of the piston rod (3) and axial bolt through-holes (25) are formed in the piston (4). The end surface (20) of the piston (4) is disposed in face-to-face contact with the end surface (23) of the piston rod (3), and under the condition bolts (22) are inserted through the bolt through-holes (25) and screwed into the threaded holes (24) to fix the piston (4) to the piston rod (3). Accordingly, the strength of a piston connecting portion can be improved with a simple structure without use of any special high-strength material for the piston rod and without any special heat treatment.

摘要： A small-sized and inexpensive air cylinder with a cushion mechanism having a simple structure is provided. Therefore, discharge outlets for discharging cushioning air are disposed in positions closer to ends of the stroke than the openings of the ports in the cylinder tube, respectively, and check valves and throttling mechanisms are arranged in parallel between discharge outlets and ports, respectively. On the outer peripheral surface of the piston, one of the piston packing rings is disposed in one position which does not pass through the opening of the port while another of the piston packing rings is disposed in another position which passes through the opening but does not pass through discharge outlet, when the piston reaches the terminal ends of the stroke.

摘要： In a pneumatic reciprocating actuator of the kind comprising a cylinder which defines a forward-motion chamber and a return-motion chamber, and a piston which is reciprocal in the cylinder and separates the forward-motion chamber and the return-motion chamber, a start stroke forwardly is initiated by admission of gaseous operating fluid from an inlet port in to the foreword-motion chamber with both the forward-motion chamber and the return-motion chamber initially at zero pressure. The operating fluid is also passed from the inlet port into the return-motion chamber during the start stroke until a back pressure of a predetermined magnitude has been produced in the return-motion chamber. Then the return-motion chamber is automatically closed by a pressure control valve unit, whereby the return-motion chamber will form a cushioning chamber for cushioning the movement of the piston in the forward direction, thereby preventing piston over speeding during the start stroke.
摘要翻译：在包括限定前进运动室的气缸和返回运动室的气动往复式致动器中，以及在气缸中往复运动并分离前进运动室和返回运动室的活塞，起动前进的行程是通过将气态工作流体从入口端口入口到前言运动室，其中前进运动室和返回运动室最初处于零压力。在起动行程中，工作流体也从入口进入返回运动室，直到在返回运动室中产生预定大小的背压。然后，返回运动室由压力控制阀单元自动关闭，由此返回运动室将形成缓冲室，用于缓冲活塞在向前方向上的运动，从而防止活塞在起动行程期间超速。

摘要： At a step of pressurizing a workpiece after reducing a speed of a piston rod at an end of a forward stroke of the piston rod by restrictively allowing compressed air to flow out of an exhaust-side pressure chamber, operation of a rapid exhaust valve is triggered by reduction of internal pressure of the exhaust-side pressure chamber to lower pressure than internal pressure of a pressurizing-side pressure chamber to thereby directly open the exhaust-side pressure chamber into the atmosphere through the rapid exhaust valve and rapidly reduce back pressure of a main piston remaining in the exhaust-side pressure chamber.

摘要： In the hydraulic tool, a main body section includes a cylinder and a piston. A head section is attached to the cylinder, includes a movable part. The piston is capable of rotating about the cylinder with the movable part. A control section is provided to the cylinder and includes oil paths and a switching valve. A piston valve reciprocally moves to control communication between a first and a second cylinder chambers. A concave is provided in a bottom face of the cylinder, escapes an end of the piston valve from a position at which the end of the piston valve contacts a bottom face, and shuts off the communication between the chambers. A projection is provided at a position different from the concave, makes the end of the piston valve contact the bottom face and allows the communication between the chambers.

摘要： A damper valve (70) located between a control valve (18) and a power steering motor (22) in a hydraulic power-assisted steering system (10). The damper valve (70) comprises a housing (72) having axially opposite first and second end portions (76 and 78) and an intermediate portion (80) interposed between the first and second end portions (76 and 78). The first end portion (76) is for fluid communication with the control valve (18) and the second end portion (78) is for fluid communication with the power steering motor (22). A flow restricting element (114) is located within the housing (72) and is movable through portions of the housing (72) including the intermediate portion (80) by fluid flow through the housing (72). The damper valve (70) further includes a biasing element (106) for restraining movement of the flow restricting element (114) toward the first end portion (76) of the housing (72). An orifice (116) is formed between the flow restricting element (114) and the housing (72) for restricting fluid flow greater than a predetermined amount through the housing (72) from the second end portion (78) toward the first end portion (76).
