Title – Polymer block impulse valve for ram pump

Description – A polymer block housing a stainless steel engine type valve, with a threaded stem for adjusting weighting and travel length. Dimensions are as required and the valve is scalable. The materials may be varied as needed and 3D printing used.

Intention – The valve allows a ram pump to be constructed from local materials and used anywhere in the world

Adaption – This valve is an adaptation of a valve made at the Motueka Community Workshop in New Zealand, established by Neil Budgen, and managed by Marcus Kempe. During its operation from 2013 to 2105, the workshop offered access to tooling machines for a NZ$20 per month fee, which provided opportunities for those with few personal resources to create new products.

The original valve made at the Motueka Community Workshop contained a standard off-the-shelf stainless steel engine valve. Details of the original conception of using a polymer block and engine valve combination as an impulse valve are unknown.
