An in-line relief valve is described having a tubular member (1) for location in a bore (2), so that compressed gas can flow from the bore (2) and through the tubular member (1), in which at higher fluid pressures gas can vent through a gap (5) provided between the bore (2) and the tubular member, whilst at lower pressures the gap is closed by a seal (8). The seal (8) may be urged by a spring (9) against a shoulder (7) in the bore. <IMAGE> |
