  • Patent number: 9572450
    Abstract: Beverage production device for producing a beverage from a single-use capsule containing a beverage ingredient, comprising: a brewing unit that receives the capsule in a cavity defined by first and second engaging members that enclose the capsule and press it at a flange-like rim in a liquid seal-tight manner. At least one of the first and second engaging members comprises a substantially annular pressing portion for applying a sealing pressure on the flange-like rim of the capsule, the first and second engaging members being configured in relative closure at the nip to leak to a liquid injected in the cavity when a capsule is not present. One of at least the first or second engaging members comprises, at its annular pressing portion, at least one passage arranged for controlling liquid leakage only within a limited angular radial direction when the first and second engaging members are closed at the nip.

  • Patent number: 5360032
    Abstract: The invention provides a control valve assembly essentially comprising a housing, a check valve member, a safety valve member as well as a support body member. The housing is provided with an inlet chamber, an outlet chamber and a back flow chamber. Between the inlet chamber and the outlet chamber, there is provided a first orifice, and between the outlet chamber and the back flow chamber there is provided a second orifice. The check valve member and the safety valve member are mounted one behind the other one in axial alignment in a support body member and form a modular unit. This modular unit is inserted into the housing such that the first orifice is closed by the check valve member and the second orifice by the safety valve member. If one or both of these valve members need service, the aforementioned modular unit can easily be removed from the control valve assembly and repaired.
