Abstract
A roll-diaphragm compressor that includes a compressor head with an interface wall that defines a concave portion and with an apex portion having an inlet port and outlet port. The roll-diaphragm compressor can also include a flexible roll-diaphragm coupled to the compressor head about an edge with the roll-diaphragm driven in a rolling motion against the interface wall. The roll-diaphragm compressor can also include a compression chamber defined by the compressor head and roll-diaphragm that is configured for receiving a fluid via the inlet port in a first state, compressing the fluid based on the volume of the compression chamber being made smaller, and expelling the fluid in a second state via the outlet port.
