  • Tool for compressing valve springs
    Patent number: 4567634
    Abstract: A tool for compressing valve springs including: a lever which has a spring engaging portion, a fulcrum portion spaced from the spring engaging portion and an axis which extends generally from the fulcrum portion to the spring engaging portion. A torque transmitting element is fitted to the lever and includes a torquing axis which extends transversely to the axis of the lever. The torque transmitting element is releasably engageable with an elongate shaft in order to establish axial alignment between the shaft and the torque transmitting element and enable the shaft and the torque transmitting element to rotate together. The torque transmitting element transmits to the lever rotational torque applied to the shaft, thereby pivoting the lever about the fulcrum portion to force the spring engaging portion to compress the valve spring.
