单件式金属孔口管和包括单件式金属孔口管的电磁阀
摘要：
根据本发明提供了一种在电磁阀(100)中使用的单件式金属孔口管(130)。该单件式金属孔口管包括金属管部分(131)，该金属管部分包括近端(140)和远端(142)，且所述远端适于延伸到所述电磁阀的电磁体(102)的电磁孔(103)内。所述单件式金属孔口管还包括在所述近端(140)内形成的孔口端(132)。该孔口端包括孔口(133)，该孔口的直径小于所述金属管部分的管内直径D，并且所述金属管部分适于滑动地接收电磁阀的电枢(105)的至少一部分。在工作时所述电枢基本阻挡和不阻挡所述孔口。
摘要（英）：

A one-piece metal orifice tube (130) for use in a solenoid valve (100) is provided according to the invention. The one-piece, metal orifice tube includes a metal tube portion (131) including a proximal end (140) and a distal end (142), with the distal end being adapted to extend into an electromagnet bore (103) of an electromagnet (102) of the solenoid valve. The one-piece metal orifice tube further includes an orifice end (132) formed in the proximal end (140). The orifice end includes an orifice (133) that is smaller in diameter than a tube inside diameter D of the metal tube portion and the metal tube portion is adapted to slidably receive at least a portion of an armature (105) of a solenoid valve. In operation, the armature substantially blocks and unblocks the orifice.
