Domestic appliance system with push-fit fluid coupling

Abstract

The invention relates to domestics appliance system which makes use of a push-fit fluid coupling () comprising a fluid feeding portion () and a fluid receiving portion () adapted to cooperate with each other to enable fluid to flow in a downstream direction (D) from the fluid feeding portion () to the fluid receiving portion (). The fluid receiving portion () comprises an actuator () comprising a fluid conduit () for fluid to flow from the fluid feeding portion () to the fluid receiving portion (). The fluid feeding portion () comprises a housing () defining a fluid flow path () and comprising an opening () in which the actuator () is intended to be inserted, a chamber () arranged in the housing () in which fluid is intended to flow, a valve seat () and a valve member () engaging the valve seat () for closing the fluid flow path (), a first piston () slidably received in the chamber () downstream of the valve member (). The fluid feeding portion () and the fluid receiving portion () are adapted to cooperate with each other such that when the actuator () is inserted in the opening (), the actuator () and the opening () cooperate with each other to form a fluid seal preventing fluid in chamber () to leak out from the chamber (), then, when the actuator () is further inserted in the opening (), the actuator () is adapted to contact the first piston () and to displace the first piston () in an upstream direction (D) until the first piston () contacts the valve member () and lifts the valve member () off the valve seat () for opening the fluid flow path () and allowing fluid to flow in the downstream direction (D). This invention prevents leak of fluid between the fluid feeding portion () and the fluid receiving portion ().
