COTTER FOR EXHAUST VALVE

This valve spring retainer exhaust ring functions as a supporting element in the exhaust valve train of older Citroën engines. The ring distributes the load of the valve spring over a small contact surface and supports stable guidance of valve movement. With a compact 4.5 mm dimension, the part fits the limited space around the valve guide. The design matches engine construction from the mid fifties to early sixties. The retainer ring operates together with valve spring and valve stem to support a proper sealing motion of the exhaust valve and helps maintain consistent positioning of related components during engine operation.
