Exhaust Vakve Redesign

Exhaust Vakve Redesign

Exhaust Vakve Redesign

(OP)
I am enquiring about redesigning a valve. The application is a compressor of some sort using an exhaust valve on the top of the cyclinder.

In some designs have a leaf lock and exhaust valve leaf in the middle of the construction like the electrolux compressor at
 http://www.electroluxcompressors.com/documents/DF4670467.pdf

they call them ('exhaust valve leaf' & 'exhaust valve retainer')

In another design these two parts have been combined into one exhaust leaf as in

http://www.electroluxcompressors.com/documents/DF569952.pdf

What I want to know is is there a major difference in performance between the two? Can they be used for the same application? Would one design be chosen over the other for a particular application and why? Are there any other differences in design that is not quite as obvious.

Thanks

Peter G.
