摘要： Self relieving seals of this invention comprise an elastomeric seal body having a first sealing surface and a second sealing surface for contact with respective drill bit sealing surfaces. The seal includes a pair of external surfaces that each extend along the seal body between the first and second sealing surfaces. The seal includes one or more relief ports that are disposed through the seal body and that have openings through each of the seal body external surfaces. The relief port can be specially configured, e.g., have different diameter sections of constant or variable dimensions, to provide a degree of control over pressure equalization through the seal body when the seal is loaded within the drill bit. The seal may include an element, e.g., solid, tubular, or porous, disposed within the relief port to provide a further desired degree of control over pressure equalization through the seal when the seal is loaded within the drill bit. Surface features, on the seal or the drill bit, can be provided to offset the relief port opening from the rock bit so that it is not blocked off. The seal can include a valve mechanism to provide a further degree of control over fluid passage through the relief port.
摘要翻译：本发明的自卸式密封件包括具有第一密封表面和用于与相应的钻头密封表面接触的第二密封表面的弹性体密封体。密封件包括一对外表面，每个外表面沿密封体在第一和第二密封表面之间延伸。密封件包括一个或多个卸载口，其设置成穿过密封体并具有通过每个密封体外表面的开口。泄压口可以被特别地构造，例如具有恒定或可变尺寸的不同直径部分，以在密封件被装载在钻头内时通过密封体提供对压力平衡的程度的控制。密封件可以包括设置在泄放口内的元件，例如固体，管状或多孔的，以便当密封件装载在钻头内时，通过密封件提供对压力平衡的进一步期望程度的控制。可以提供在密封件或钻头上的表面特征以将卸载口开口偏离岩石钻头，使得其不被堵塞。密封件可以包括阀机构，以进一步控制通过排放口的流体通道。
