摘要： A fluid pressure cylinder includes a cylinder body, a piston accommodated in the cylinder body to define first and second pressure chambers therein, means for supplying fluid to each chamber to reciprocate the piston between a first stroke end and a second stroke end, first and second bumper surfaces, an annular cushion retainer connected to the first bumper surface, and an elastomeric cushion for deforming and cushioning an impact produced when the piston reaches the first stroke end. The bumper surfaces approach each other when the piston reaches the first stroke end and separate from one another when the piston moves toward the second stroke end. The cushion has a shape corresponding generally to a hollow conical section. The cushion includes a base section retained by the cushion retainer and a buffer section joined to the base section. The buffer section has an outer surface for contacting the second bumper surface and an inner surface that faces the first bumper surface. The outer surface forms a circular seal with the second bumper surface when the piston approaches the first stroke end. The cushion is flexed such that the buffer section moves toward the first bumper surface. The buffer section moves away from the first bumper surface when the piston moves towards the second stroke end.

摘要： Disclosed is a rodless cylinder having a cylinder barrel with a slit formed axially therein. A piston is movably housed in the cylinder barrel. A mounting table is disposed movably along the external surface of the cylinder barrel and connected to the piston through the slit. An external actuator is mounted on the mounting table and designed to be driven by a pressure fluid. A passage, through which a pressure fluid can pass, is defined in the cylinder barrel. An inlet is provided in the cylinder barrel so as to introduce the pressure fluid in the passage to the mounting table side. An outlet is provided on the mounting table so as to supply the pressure fluid introduced from the inlet to the external actuator.

摘要： Disclosed is a rotary actuator utilizing magnetic screws which are stably rotatable at a great torque with little torque variation. The rotary actuator comprising (a) a closed hollow cylinder, a piston sliding within the cylinder, and a rotary shaft which rotates with the sliding of the piston, has (b) a first magnetic screw member which makes a linear motion in synchronism with the sliding of the piston, and is provided with a first spiral magnetized band, and (c) a rotary shaft rotatably supported in relation to the first magnetic screw member, and having a second magnetic screw provided with a second spiral magnetized band. (d) With the sliding of the piston, the second magnetic screw receives the magnetic force from the first magnetic screw to thereby rotate the rotating shaft.

摘要： An axial air motor having a plurality of cylinders disposed around the axis of rotation of an output shaft in such a manner that the direction of movement of the pistons is parallel with the output shaft. The air motor is provided with a swash plate which is rotatably mounted on the output shaft through a bearing and which is directly pressed by means of a ball which is mounted on each piston. Accordingly, the structure of the motor as a whole is simplified and the frictional resistance occurring between constituent parts can be minimized. Thus, it is possible to achieve an efficient axial air motor. Further, since a lubricant can be charged in a hole for receiving the ball in advance, it is possible to reduce the frictional resistance occurring between the ball and the swash plate even in a non-lubricated operation.
摘要翻译： 一种轴向空气马达，其具有以输出轴的旋转轴线设置的多个气缸，使得活塞的运动方向与输出轴平行。 气动马达设置有斜盘，其通过轴承可旋转地安装在输出轴上，并且通过安装在每个活塞上的球直接按压。 因此，电动机的整体结构简单化，能够使构成部件之间产生的摩擦阻力最小化。 因此，可以实现有效的轴向空气马达。 此外，由于可以预先将润滑剂填充在用于接收球的孔中，所以即使在非润滑操作中也可以减小球和斜盘之间产生的摩擦阻力。
