Abstract: A mechanism and method is provided for preventing instantaneous unlatching of a driving and a driven member upon an accidental drop in the hydraulic-holding pressure. One embodiment of the mechanism includes a housing having an inlet port connectable to a substantially sustained high pressure fluid source; and a configured locking pin axially displaceable to an engaged position with respect to the inlet port in response to high pressure fluid entrapped in the housing. The locking pin is spring-biasingly axially displaceable to a disengaged position when the pressure is low. The axial displacement of the locking pin sufficiently overlaps the inlet port to form a variable orifice so that the rate of exhausting of entrapped fluid is variable. In another embodiment, the entrapped fluid is slowly exhausted until a seal length is reduced to zero by the retraction of the locking pin. In another embodiment, latching and unlatching is controlled by pressure pulses. In the latched state, contact between positively-engaged parts negates the need for sustained high fluid pressures.

Abstract translation: 提供一种机构和方法，用于防止在液压保持压力的意外下降时驱动和从动构件的瞬时解锁。 机构的一个实施例包括具有可连接到基本上持续的高压流体源的入口的壳体; 以及配置的锁定销，其响应于捕获在壳体中的高压流体而轴向移位到相对于入口的接合位置。 当压力低时，锁定销弹簧偏置地轴向移动到脱离位置。 锁定销的轴向位移与入口端口充分重叠以形成可变孔口，使得截留流体的排出速率是可变的。 在另一个实施例中，捕获的流体被缓慢排出，直到通过锁定销的缩回将密封件长度减小到零。 在另一个实施例中，通过压力脉冲控制闭锁和解锁。 在锁定状态下，正向啮合部件之间的接触不需要持续的高流体压力。

Abstract: A switch element (1) is proposed for valve shut-off, fabricated as cam follower for a plunger rod valve drive of an internal combustion engine, having an outer part (2) and an inner element (4) axially movable in its bore (3) and with rotational security (15) relative to the guided inner element (4). The outer part (2), inside the bore (3), has an annular groove (6), and the inner element (4) has a radial bore (7) with two diametrically opposed pistons (8), which to couple the elements (2, 4) in their axially remote relative position achieved by a lost-motion spring (5) are displaceable towards the annular groove (6). On their cam-side under side, emanating from their radially outward, bulbous face, the pistons (8) segmentwise comprise a plane transverse surface as contact area for a facing under side (27) of the annular groove (6). The latter is intersected by two diametrically opposed oil ports (11) running offset 90° from the pistons (8) in circumferential direction. In addition, the outer part (2) has means (13) for rotationally secured guidance of the switch element (1) relative to a surrounding structure.
