Abstract
The invention contemplates an improved poppet-type relief-valve construction which features an inlet-port configuration at upstream offset from the valve-closed seat region of the valve. To open the valve, a valve member must be moved by upstream pressure exceeding a predetermined threshold. This valve member integrally carries a specially profiled formation that (a) is upstream from the seat region and (b) coacts with a specially profiled region of inlet port. This action necessarily takes place upstream from the seat region and is such as to provide control of valve operation especially during that fraction of valve-member displacement that spans the 'cracking' phase of valve operation. The net result is to avoid development of the 'chatter' which customarily characterizes the 'cracking' phase of valve operation.
