摘要： An electroexpansive linear actuator utilizes a sagittal tension member to amplify linear motion in which the electroexpansive member is placed in compression between a fixed base support and a lever support member hingedly connected to the fixed base. One end of the sagittal tension member is attached to the fixed base while the other end is attached to the lever support member distal the hinge point. The device to be actuated is connected proximate the midpoint of the sagittal tension member and moves perpendicular to the longitudinal axis of the sagittal tension member when the electroexpansive member expands and contracts. A second embodiment of the actuator utilizes a second lever support arm instead of the fixed base as a bearing support for the other end of the electroexpansive member.

摘要： A fuel pump for providing fuel at relatively high pressure is activated by gas pressure, created during the compression stroke of an internal combustion engine. The pump includes a piston and a hollow plunger which are biased by a single spring in opposite directions. The piston, which is exposed to gases in the engine's cylinder, is urged, by the gas pressure in the cylinder during the compression stroke, to move upwardly. A limit is placed on the piston's upward stroke. When reaching the upward limit the pressure which is applied to fuel in a fuel chamber is only a function of the force applied by the spring to the plunger. When fuel ejection is enabled, the spring pushes the plunger toward the fuel chamber to eject the fuel therefrom. Toward the end of the exhaust stroke the piston moves toward the engine cylinder, forcing the plunger to move in the same direction until the latter's travel is limited by limiting means. Fuel is then injectable into the fuel chamber for subsequent ejection.
摘要翻译：用于在较高压力下提供燃料的燃料泵由在内燃机的压缩冲程期间产生的气体压力激活。该泵包括一个活塞和一个中空的柱塞，它们以相反的方向被单个弹簧偏压。暴露于发动机气缸内的气体的活塞被压缩冲程中气缸内的气体压力向上移动。活塞向上行程有一个限制。当达到上限时，施加到燃料室中的燃料的压力仅仅是由弹簧施加到柱塞的力的函数。当启用燃料喷射时，弹簧将柱塞推向燃料室以从其中排出燃料。在排气行程结束时，活塞朝向发动机气缸移动，迫使柱塞沿相同的方向移动，直到其运动受到限制装置的限制。燃料然后可以注入到燃料室中用于随后的排出。
