Abstract
A compression pump has a bladder that is supported during the compression stroke on the low-pressure side of the bladder, and that can have a compression cavity that is fully evacuated during each stroke. The compression pump can have a housing with an entrance section, a center section, and a crown section. The entrance and center sections define seats to receive bridge bearings (of bridges each having a rod and a bearing). A piston can have an inlet section, a middle section, and a head section. The inlet and middle sections define seats to receive groove bearings. The bridges and groove bearings structurally hold a support structure, which supports the bladder. The support structure can be a slide support that changes shape as the piston moves within the housing. The piston head can have a valve seat that the inlet valve head is received within when it is closed.
