摘要： The present invention provides an improved electric drum brake (10). The electric drum brake (10) utilizes vibration absorbing mount (27) for positioning an electro-magnet (24) on the tang (22) of an actuating lever (21). The vibration absorbing mount (27) prevents metal-to-metal contact between the tang (22) and the electromagnet (24) and eliminates or greatly reduces road vibrations.

摘要： An air over oil high pressure modulating valve comprising dual acting valve members wherein one of said valves is responsive to air pressure acting thereon for opening the other of said valves for directing controlled hydraulic fluid pressure to a brake apparatus, or the like. Upon the application of pneumatic pressure against the first valve member, the second valve member is opened for releasing hydraulic fluid pressure to the brake apparatus for actuation thereof. Upon the release of pneumatic pressure from the first valve member, the second valve member is maintained in a closed position for retaining the hydraulic fluid in a fluid chamber which is in communication with a fluid accumulator. When the pneumatic pressure acting on the first valve is only partially released, the first valve opens communication between the open second valve and the fluid accumulator for reducing the fluid pressure at the brake apparatus.
摘要翻译：一种空气过油高压调节阀，包括双作用阀构件，其中所述阀中的一个响应于作用在其上的空气压力来打开另一个所述阀，以将受控的液压流体压力引导到制动装置等。当对第一阀构件施加气动压力时，第二阀构件被打开以释放用于致动其的制动装置的液压流体压力。当从第一阀构件释放气动压力时，第二阀构件保持在关闭位置，用于将液压流体保持在与流体储存器连通的流体室中。当作用在第一阀上的气动压力仅部分释放时，第一阀打开打开的第二阀和流体蓄压器之间的连通，以减小制动装置处的流体压力。
