Abstract

The invention relates to a pressure regulator for use in a breathing apparatus assembly, and more particularly, but not exclusively, to a piston type pressure regulator having a dry ambient chamber. The pressure regulating valve is suitable for use in a diving application and includes a body (20) having a flow passage therethrough and a valve seat (25) located in the flow passage. The valve also includes a valve closure (30) being displaceable between a closed position in which the valve closure1 abuts the valve seat so as to close the flow passage, and an open position in which the valve closure is displaced from the valve seat so as to open the flow passage and biasing means (40) for exerting a bias on the valve closure. The valve is characterized therein that it includes force imparting means (50) adapted to impart a force on the biasing means in order to adjust the bias exerted by the biasing means, the force imparting means being subjected to an ambient pressure in which the pressure regulating valve operates.
