Abstract

The invention relates to a vacuum regulator (1) for maintaining a substantially constant vacuum in a vacuum system (2). The vacuum regulator (1) includes a main valve arranged to control a supply of air to the vacuum system (2). The main valve includes a valve seat (3) defining a passage (4) arranged to lead air to the vacuum system (2) and a valve body (5) moveably arranged in a direction between a closed position and a maximally open position in order to regulate the size of a minimum flow area (18) between the valve seat (3) and the valve body (5). A force (19) caused by the vacuum acts on the valve body (5) in a direction towards the closed position. The valve seat (3) and the valve body (5) have such a design, that the value of the force (19), in a continuous way, increases with the degree of opening of the valve body (5).
