ABSTRACT:
A packing for a piston-and-cylinder arrangement, especially for a dosing or metering unit for highly-filled reactive synthetic resin components such as a polyol or isocyanate, e.g. for producing polyurethanes, comprises a stack of yieldable rings of V-section with one member at an end of the stack bearing with a planar surface against a planar shoulder of the piston and the ring at the opposite end of the stack engaging a spring ring of V-section which confronts an abutment of the piston. According to the invention, the angle .alpha. between the two shanks of the V of the spring ring, in its unstressed state, is greater than the angle .gamma. between the flanks of the packing ring at this end of the stack which define the V of this packing ring. The arrangement is such that under stress the angle .alpha. can be reduced to a value less than the angle .gamma..
