ABSTRACT:
A device which in normal use restricts relative movement between two members to one direction. Attempted movement opposite to the one direction causes an hydraulic lock to prevent such attempted movement, which also causes wedges actuated by the hydraulic lock to engage in locking co-operation to prevent the attempted movement instead of or in unison with the hydraulic lock.
