Abstract
A connector for conveying hydraulic pressure from a relatively fixed source to a relatively moveable hydraulically actuable arrangement is described. The connector comprises a telescoping assembly of hollow members opposite ends of which have means for joining the connector to hydraulic lines. A first of the telescoping members is formed with an integral annular chamber which is swept by annular piston means carried by a second of the telescoping members interengaged with the first. Dimensions are chosen so that a change in the internal volume of the telescoping members is compensated by the volume displaced by movement of the piston in the chamber whereby the total internal volume of the system remains constant.
