Patent number: 6955506Abstract: A device for pneumatically conveying bulk material has at least one flow limiter arranged in a conveying airstream. The flow limiter has a housing and at least one control member arranged in the housing. The control member controls a flow velocity of the conveying airstream as a function of a dynamic pressure differential. The position of the at least one control member in the housing is determined by an equilibrium between a restoring force acting on the at least one control member and an opposed force oriented in a direction opposite to the restoring force. The opposed force is caused by the dynamic pressure differential and acts on the at least one control member.Type: GrantFiled: March 23, 2004Date of Patent: October 18, 2005Assignee: Motan Holding GmbHInventors: Holger Kühnau, Guido Mayer
