摘要 |
A brewing apparatus includes a vertically movable cylinder with an open top and bottom, a piston mounted for reciprocation down into such cylinder and a heated liquid supply device for discharging brewing liquid into the open top of the cylinder. A brewing cavity is horizontally reciprocal beneath the cylinder between a brewing position and a discharge position. A ground beverage material supply delivers material into the brewing cavity when the cavity is disposed at a material supplying position located intermediate the brewing position and the discharge position. A seal element which is disposed on the outer peripheral surface of the piston to obtain sealing between the piston and cylinder comprises a ring portion affixed to the piston and the flange portion extending radially outwardly from the end portion of the ring portion. A cut out space is formed on the inner surface of the flange portion which connects with the ring portion.
