Abstract
A cryogenic pump for pumping cryogenic fluid is provided. The pump includes a pump assembly adapted for exposure to cryogenic fluid that includes a plurality of pumping elements disposed about a pump axis. A drive assembly drives the pumping elements to pump cryogenic fluid. A plurality of actuating elements are arranged circumferentially about the pump axis, each actuating element operatively interconnecting the drive assembly with a respective one of the pumping elements. Each actuating element includes a first portion disposed a first radial distance from the pump axis and a second portion disposed a second radial distance from the pump axis with the first radial distance being less than the second radial distance at ambient temperature.
