Abstract

An actuator, such as a pressure actuator or a vacuum actuator, has a housing and a plunger that is guided through the housing. A diaphragm is connected to the housing and to the plunger and forms a gas-tight pressure chamber with the housing. A pressure medium connector is provided on the housing and communicates with the pressure chamber to pressurize the pressure chamber. A braking element is provided on the plunger and enables a braking force can be exerted on the plunger.
