Pump for liquid beverage preparation devices
DCFirst Claim
1. A device for the preparation of a liquid food or beverage from a portioned ingredient placed within a beverage preparation chamber, the device comprising:
- a housing,a pump comprising a pump chamber that contains a piston moveably mounted therein and vibrates during use, for displacing a liquid from a pump inlet to a pump outlet,a liquid supply which is in fluid connection with the liquid inlet of the pump, anda pump support securing the vibrating pump chamber to the housing,a duct that is mechanically connected to the housing and to one of the pump inlet or pump outlet and that is arranged to guide liquid from or to the pump,wherein the pump support comprises an elastic support member for resiliently supporting the vibrating pump chamber in the housing, andwherein the duct is rigid and connected with the pump inlet or pump outlet by an elastic sealing member for resiliently connecting the rigid duct to the vibrating pump chamber.

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.
