Abstract: An actuator assembly (10) includes a cylinder (26) disposed in an actuator housing (14), the cylinder having a cylinder interior (32) is in fluid communication with a source of pressurized fluid (36). A ram member (40) has a piston head (46) within the cylinder interior, and pressure on the piston head moves the ram member. An end of the ram member acts on a collar (50) having a collar interior (54), and an end of a rod member (82) is disposed within the collar interior. The rod member is displaceable relative to the collar such that the end of the rod member does not contact the collar. Accordingly, fluid in the cylinder interior acting on the ram member may expand due to thermal expansion without damaging a hard stop (129) at an opposite end of the rod member and without losing system pressure by triggering a relief valve.

Abstract translation: 致动器组件（10）包括设置在致动器壳体（14）中的汽缸（26），汽缸具有汽缸内部（32），其与加压流体源（36）流体连通。 冲头构件（40）在气缸内部具有活塞头（46），并且活塞头上的压力使冲头构件移动。 压头构件的一端作用在具有套环内部（54）的套环（50）上，并且杆构件（82）的一端设置在套环内部。 杆构件可相对于套环移位，使得杆构件的端部不接触套环。 因此，缸体内部的作用在冲杆构件上的流体可由于热膨胀而膨胀，而不会损坏杆构件的相对端处的硬止动件（129），并且不会通过触发泄压阀而损失系统压力。
