    • A valve spring compressor apparatus for removing and installing valve springs on automotive racing engines includes a valve seat and a compressor pump assembly. The valve seat is placed between the valve spring and the engine housing. The compressor engages the valve spring seat with a support arm and extends a piston toward the valve spring seat, thus compressing the valve spring and allowing for the removal of the retainer ring and keeper lock. The compressor uses a source of compressed air to drive a power piston into a compression chamber multiplying the supply air pressure several times. This multiplied air pressure is retained in the extension piston chamber by a one-way valve. As the extension piston extends, the multiplied air pressure in the extension piston is maintained by repeated cycling of the compressor.
    • 用于在汽车赛车发动机上拆卸和安装阀弹簧的阀弹簧压缩机装置包括阀座和压缩机泵组件。 阀座位于阀弹簧和发动机壳体之间。 压缩机通过支撑臂与阀弹簧座接合并且将活塞朝向阀弹簧座延伸,从而压缩阀弹簧并允许拆卸保持环和保持器锁定。 压缩机使用压缩空气源将动力活塞驱动到压缩室中,使供气压力倍增。 该倍增空气压力通过单向阀保持在延伸活塞室中。 当延伸活塞延伸时,通过压缩机的重复循环来维持延伸活塞中的倍增空气压力。
