A system that occurs when air or other fluid is enclosed within a metal cylinder containing an element. Pneumatic or hydraulic pressure can be applied in a simple manner without any problems associated with the ring. The purpose is to provide more linear reciprocating motion. In other words, to perform a controlled movement The present invention provides an inexpensive and simple alternative to conventional piston-cylinder assemblies. is planned.

本発明によれば、この課題は、流体式駆動装置内のロッドが上記の可撓性折畳み 可能部材と共に、駆動装置の作動に必要な圧力流体用の流体室を完全に区画形成 し、例えばエラストマー類の上記部材が畳み込み式の薄膜からなり、ロッドに対 するシーリング例えばリップシーリング？もたらすことにより解決される。According to the present invention, this problem is solved when the rod in the hydraulic drive device is Completely demarcates the fluid chamber for the pressurized fluid required for actuation of the drive unit, together with possible components However, for example, the above-mentioned elastomer material is made of a foldable thin film and is attached to the rod. For example, lip sealing? Solved by bringing.

次に、本発明による流体式駆動装置の実施形を軸線方向断面図で示している添附 図面を参照しつつ本発明を更に詳細に説明する。Next, we will refer to the attached appendix showing an axial cross-sectional view of an embodiment of the fluid drive device according to the present invention. The present invention will be explained in more detail with reference to the drawings.

図示された実施形において、流体式駆動装置は、端壁１１．１２を有するハウジ ング乃至シリンダ１ｏを具備している。これら端壁には、直線状運動用の出方ロ ッド１３が装着されている。該ロッド１３は端壁１１．１２間に圧力板体１４を 担持支承している。圧力板体１４の各側には、好ましくはゴム製の薄膜１５とロ ッド１３とにより圧力室が区画形成されている。各端壁には圧力流体用の連通部 材１６が設けられている。In the illustrated embodiment, the hydraulic drive device includes a housing having an end wall 11.12. It is equipped with a cylinder 1o. These end walls have exit rods for linear motion. head 13 is attached. The rod 13 has a pressure plate 14 between the end walls 11,12. Supporting and supporting. On each side of the pressure plate 14 is a thin membrane 15, preferably made of rubber. A pressure chamber is defined by the pad 13. Each end wall has a connection for pressure fluid A material 16 is provided.
