<p>A mechanical detent for engaging a valve spool having a linear element wire spring positioned transverse to the valve spool for engaging circumferential grooves in the spool. The linear element spring includes a single wire spring having a triangular or square shape, or alternatively, one or more non-integral straight wire springs. Extensions of the linear element spring extend a distance away from the spool that is greater than the spring wire diameter. The extensions allow the spring to be movable out of the groove, while still permitting a small diameter spring wire.</p> |
