Abstract (en)
The pump (300) has an intake opening (302) closed by a non-return valve (314), and a discharge opening (304) closed by another non-return valve (316). An armature plate (328) represents a part of an electromagnetic regulating unit for a pumping stroke together with an armature (330). A pump volume (340) is formed by an inner area (342). Metallic bellows (322) i.e. stainless steel bellows, are connected to a housing base (354). A base body projects between the plate and the bellows. The inner area has a prechamber and a working chamber, where the plate has an attachment element. The non-return valves are designed as ball seat valves. An independent claim is also included for a method for starting a pump.
