Abstract
Devices for the preparation of a liquid food or beverage. One device includes a housing, pump, pump support for securing the pump to the housing, a rigid duct that is connected by an elastic sealing member to the housing and to an inlet or outlet of the pump. The pump support includes an elastic support member for resiliently supporting the pump chamber in the housing. Another device includes a pre-suction chamber connected to a liquid inlet of a pump and being designed to intermittently provide liquid to said liquid inlet. A further device includes a connector of at least one elastic sealing member designed to absorb vibrations from a pump of the device and to enable a relative movement of a duct and a liquid inlet or outlet of the pump.
