摘要： A plunger (10) for intermittently delivery counterblow air to a gob of glass at a formable temperature in a blank mold of a I.S. glass container forming machine that is being operated on the blow and blow process. The plunger comprises a fixed annular member (12) with an enlarged recess (12a) at an inlet end and a valve seat (12d) at an upper end. The plunger also has a sliding valve member (14) within an annulus of the annular member (12), and the valve member (14) has a stem portion (14a) and an enlarged valve seat portion (14b) at a free end thereof. The plunger further has a collar (16) threadably and adjustably secured to the stem portion of the sliding valve member, and the collar, which is slidable within the recess of the annular member, has a plurality of air flow passages (16a) extending therethrough. Pressurized air is intermittently delivered to the recess of the annular member (12) through an inlet line (20), which has an on/off valve (22) therein. When the recess of the annular member (12) is pressurized, pressure therein will act on an underside of the collar to lift the collar and the valve member, jointly, with respect to the annular member, and thereby unseat the valve portion of the valve member from the seat of the annular member. This will permit pressurized air to flow from the recess of the annular member through the air flow passages in the collar, and then outwardly from the plunger through a gap between the valve portion of the valve member and the valve seat of the annular member. Upon the depressurization of the recess of the annular member, the valve member and the collar will return, by gravity, to a position where the valve portion of the valve member is seated against the valve seat of the annular member.
摘要翻译：一种柱塞（10），用于在I.S.的坯模中以可形成的温度间歇地将反吹的空气输送到玻璃料滴。玻璃容器成型机正在吹吹过程中运行。柱塞包括固定的环形构件（12），其在入口端处具有扩大的凹部（12a），在上端具有阀座（12d）。柱塞还在环形构件（12）的环形空间内具有滑动阀构件（14），并且阀构件（14）在其自由端处具有杆部分（14a）和扩大的阀座部分（14b）。柱塞还具有螺纹和可调节地固定到滑动阀构件的杆部的轴环（16），并且可在环形构件的凹部内滑动的套环具有多个气流通道（16a），该空气流动通道。加压空气通过其中具有开/关阀（22）的入口管线（20）间歇地输送到环形构件（12）的凹部。当环形构件（12）的凹部被加压时，其中的压力将作用在套环的下侧，以相对于环形构件共同提升套环和阀构件，从而使阀的阀部分离开构件从环形构件的座位。这将允许加压空气从环形构件的凹部流过套环中的空气流动通道，然后通过阀构件的阀部分和环形构件的阀座之间的间隙从柱塞向外流动。当环形构件的凹部减压时，阀构件和套环将通过重力返回到阀构件的阀部分抵靠环形构件的阀座的位置。
