Abstract:
1. A device for dispensing a heated liquid, comprising: a dispenser body including a liquid inlet configured to receive the heated liquid, a liquid passage in communication with said liquid inlet, an outlet in communication with said liquid passage to dispense the heated liquid, and a valve element including an outer surface and a circumferential groove in said outer surface of and around said valve element, said dispenser body further including an inner surface defining a recessed portion cooperating with said groove to define a cavity about said valve element, said valve element adapted to move relative to said recessed portion to selectively allow and prevent flow of the heated liquid through said outlet from said liquid passage; an actuating element operatively coupled to said valve element to control dispensing of the heated liquid through said outlet; and a flexible seal situated within said cavity defined by said recessed portion cooperating with said groove and spaced from said actuating element, a first portion of said seal being configured to form a fluid tight seal within said recessed portion and a second portion being configured to form a fluid tight seal within said circumferential groove about said valve element during reciprocation of said valve element relative to said recessed portion thereby preventing liquid from leaking out of said liquid passage past said flexible seal.
