摘要： The invention relates to a coffee percolator for selectively making normal coffee or espresso, comprising a water flow path extending between a cold water supply inlet and a brewing unit, said flow path being divided into a first branch including a pressure pump, and a second branch including a valve adapted to close or be closed in the espresso making mode, and further comprising control means for activating said valve(s) and/or said pump in response to the selection of the type of coffee to be made. The invention is directed towards the provision of a coffee percolator of this type, which is of simplyfied and economic construction and substantially failure-proof. This is achieved by providing that the flow path is employed in common for the water used for making espresso and normal coffee, and is only divided adjacent the pump into the first flow path branch including the pump and the second flow path branch forming a bypass across the pump. This construction eliminates a considerable number of connection and sealing points along the flow path and at the metering and heating devices, resulting in the elimination of potential failure at these locations.

摘要： A drive system for side-by-side piston pumps connected to beverage concentrate containers in a post-mix beverage dispenser system is described. An electric motor rotates a drive shaft in either a forward or reverse direction for the selective actuation of one or the other of the piston pumps. First and second hollow shafts are concentrically disposed around the drive shaft, one hollow shaft being mechanically coupled through a cam and lever arrangement to each of the piston pumps. Free-wheeling clutches are provided between the drive shaft and each of the respective hollow shafts such that one hollow shaft is coupled to rotate with the drive shaft in the forward direction of rotation of the drive shaft and the other hollow shaft is coupled to rotate with the drive shaft in the reverse direction of rotation of the drive shaft.
