Abstract
The present invention provides a seal assembly for sealing between two relatively slideable members of non-circular cross-section. A plurality of adjacent seal members may be staggered and grouped within a groove so that all leakage surfaces between the two relatively slideable members are sealed. Multiple seal members or seal member groups may be used to reduce leakage caused by incomplete contact of the seal members with leakage surfaces. An actuator system may comprise various embodiments of the present invention to enable the actuation of one member in relation to another.
