Abstract (en)
[origin: EP2161455A1] The dual pump (5) has pipes (20, 25) ending in a common outlet pipe (30). The pipes are provided at a high pressure side of two pumps (10, 15) of the dual pump. A check valve (35) is arranged in an opening region (27) in a flow controlled manner. One of the pipes blocks the other pipe during the flow. The check valve has two flow surfaces (80, 85) projecting in a flow path in a closing position. The flow surfaces are turned in an upstream manner. The flow surfaces are formed by a spoiler that is arranged at the check valve, and encircled by two sealing surfaces (65, 70).
