An exhaust valve (10), particularly for a blood pressure measuring apparatus, comprising a valve seat (31) disposed along the course of an outlet channel in a valve housing (11) and oriented toward the pressure side of the valve. A valve body (25) having the form of a slender conical frustum arranged on the pressure side of the valve seat (31) cooperates with the valve seat. Valve body (25) is urged against the valve seat (31) by a closing spring (27). To facilitate controlled release of an elevated pressure contained by the valve, a screw cap (37) is arranged on the valve housing (11) along the axial projection line of the valve body (25), and the valve body (25) is connected to the screw cap (37) through a support bearing (43). A two-stage steep thread (44,45) is provided between the screw cap (37) and the valve housing (11).
