    • A push button combination lock type gas cap and an actuator forming a part thereof, takes the form of a casing which may be mounted to an open end of a fuel tank filling neck with a stopper mounted within the casing for movement between a first position in which the cap is removable from the filler neck, and a second position where the cap is locked thereto. A first center push button mounted on the casing for movement in the direction of its axis between projected and depressed position, shifts the stopper to the first position for locking the cap to the filler tube upon depression thereof. The first push button is maintained in depressed position with a laterally shiftable slide plate operatively engaging the first push button for normally preventing retraction of the first push button absent a selective depression of one or more of a plurality of second push buttons mounted circumferentially about the center push button. The second push buttons are also normally held in depressed position, unless further depressed and released. Spline engagement between the push buttons and casing bores alternatively lock the depressible push buttons in initial depressed position and subsequent projected position. Rotatable pods beneath the depressible push button, engage lock pins having side recesses which when aligned with holes within the slide plate receiving the lock pins permit lateral shifting of the slide plate to release the first push button.
    • 按钮组合锁式气帽和形成其一部分的致动器采取壳体的形式,壳体可以安装到燃料箱填充颈部的开口端,安装在壳体内的止动件用于在第一位置 帽可以从加注颈部移除,以及第二位置,其中盖被锁定在其上。 安装在壳体上的第一中心按钮,用于在其突出和凹陷位置之间沿其轴线的方向移动,将止动器移动到第一位置,以在压下时将盖锁定到加注管。 第一按钮保持在按压位置,其中横向可移动的滑动板可操作地接合第一按钮,用于正常地防止第一按钮的缩回,而不选择性地按压围绕中心周向安装的多个第二按钮中的一个或多个 按钮。 第二按钮通常也保持在按压位置,除非进一步按压并释放。 按钮和套管孔之间的花键接合将可压下的按钮交替地锁定在初始按压位置和随后的突出位置。 在可按压的按钮下面的可旋转荚接合具有侧凹槽的锁定销,当与接收锁定销的滑动板内的孔对准时,该凹槽允许滑动板的横向移位以释放第一按钮。
