Abstract

The invention relates to a spring brake cylinder with an emergency release device, comprising the following: a housing in which a spring-loaded piston can be moved axially with a piston rod, at least one spring-loaded spring, wherein the emergency release device comprises an actuation device, an emergency release mechanism to interrupt the power transmission between the spring-loaded piston and the piston rod and a holding device for holding the emergency release device in a transmission condition. The invention further includes a blocking device to prevent the holding device from holding of the emergency release mechanism in a transmission position when the spring-loaded piston only partly released
