Abstract: Upper and lower support members, supporting a valve, are lowered toward a valve guide with at least the lower support member vibrated by a vibrating device. When a lower-end chamfered surface of the valve has failed to be brought into contact with the opening edge of the guide through the lowering, not only the upper support member is caused to gradually move away from an umbrella section of the valve but also the position of supporting, by the lower support member, of a shaft section of the valve is displaced downward after the lower end of the shaft section of the valve contacts the upper end surface of the guide, so that vibrating movement of the lower end of the shaft section is reduced to allow the chamfered surface to contact the opening edge. Then, the valve is inserted into the guide by a pressing member.

Abstract: In a fastening portion for fastening an upper retaining portion and a lower retaining portion by means of a mounting screw, the upper retaining portion has a screw hole and a cylindrical guide formed around and above the screw hole. Further, a projection is formed on the inner wall of the cylindrical guide at an upper portion thereof.

Abstract: A tool for mounting of disk valves in motor cylinder heads includes a shaft and a spring-loaded tap that may be pressed into the shaft, and two vaulted clamping arms placed on opposite sides of the shaft, with the purpose of holding two locking bodies in connection with the occasion when these bodies are to be transferred to the rod of the valve. On the individual clamping arm there are protrusions that protrude relative to an axially straight inside on the clamping arm and serve as carriers for the individual locking body. Each protrusion has support surfaces that are obliquely positioned relative to the clamping arm in order to hold a convexly vaulted outside on the locking body placed against the concave inside of the clamping arm, when the locking body is dislocated from the tap to grooves in the valve rod, thereby distancing the front edge of the locking body from the external envelope surface of the valve rod.

Abstract: A method and apparatus for reliably placing the spring retainer and keys on a valve stem, to lock the valve spring in place. The apparatus includes a linear actuator, having an extended position and a retracted position, and a connector for connecting the linear actuator to a carrying member, such as a robotic arm. A gripper is attached to the linear actuator, adapted to grip the spring retainer.
