Abstract
This invention relates to an improvement in a reciprocating piston type pump having spaced radially expanding packings which are expandable in response to axial pressure on the packings. There is also included a compression spring between the packings. The pump contains means to vary the compression of the compression spring dependent upon the pressures within the pump during operation.
