<p>A pressure regulator comprises a high-pressure chamber (2), and an atmospheric pressure chamber (3) having an opening (4) for controlled high-pressure (C), between which a diaphragm (5) is disposed having a sealing disc (6) resiliently movable in relation thereto, said diaphragm (5) selectively closing both an atmospheric pressure input port (8) and a through port (7) between high-pressure chamber (2) and atmospheric pressure chamber (3) in the sealing disc (6), and said sealing disc (6) being pressed towards the diaphragm (5) under the action of at least one spring (9). In order to permit a control of the high-pressure dependent on atmospheric pressure, for example of the boost pressure of a turbo charger for internal combustion engines, the pressure regulator has a bellow (11) responding to changes in the atmospheric pressure (A) for changing the bias of the spring (9) upon changing atmospheric pressure (A). The action of the bellow (11) on the spring bias is expediently adjustable.</p> |
