Fuel supply device

The invention relates to a fuel supply device. The fuel supply device has a housing and an intake channel section formed in the housing. At least one fuel port opens into the intake channel section. At least one fuel channel is provided and a valve with valve plate is arranged in the fuel channel. The valve has a closed position and an open position. The valve plate contacts a valve seat in the closed position. The valve plate carries out a valve stroke between open position and closed position. At least one annular gap is formed in the fuel channel. A gap width of the at least one annular gapis matched to a length of the valve stroke of the valve plate such that the gap width is not larger than twice a length of the valve stroke. A flow cross section of the annular gap is larger than a flow cross section of the valve. 本发明涉及一种燃料供应装置，其具有壳体，在壳体中构造有抽吸通道区段。至少一个燃料开口通入到所述抽吸通道区段中。所述燃料供应装置具有至少一条燃料通道，在所述燃料通道中布置有阀。所述阀具有小阀板。所述阀具有如下关闭位置，在所述关闭位置中，所述小阀板贴靠在阀座上，并且所述阀具有打开位置。所述小阀板在所述打开位置与所述关闭位置之间经过阀行程。在所述燃料通道中形成环形间隙，其中，所述环形间隙的
