Abstract
A pressure sensor for a brake booster includes a housing that receives a pressure sensor element and which has a first fluid connection, via which the pressure sensor can be connected to the brake booster. The housing has a second fluid connection with a receiving opening which at least partly receives a flow valve and a connection socket for a vacuum pump, wherein the flow valve releases the flow of fluid in the direction of the vacuum pump and blocks the flow of fluid in the opposite direction. The flow valve is designed as a membrane insert and is inserted into the receiving opening.
