Abstract
A linear pump and motor system includes a motor, rotary-to-linear mechanism, pressure compensation device (PCD), and gas mitigation assembly. The rotary-to-linear mechanism may translate rotation of a motor into linear motion to provide a pumping action. A PCD may minimize a pressure differential between lubrication fluids and external fluids. A gas mitigation assembly may provide a mechanism that mechanically opens a valve. In some embodiments, a PCD may be utilized separately from the linear pump. In some embodiments, a gas mitigation assembly may be utilized separately from the linear pump.
