Abstract
The landing gear systems, methods and apparatuses disclosed herein may comprise a shrink pump and an unshrink valve that are capable of shrinking a landing gear shock strut up to about 40% of its available stroke. The shrink pump may be configured to pump fluid (e.g., a hydraulic fluid) between an oil chamber, where hydraulic fluid is likely present and a shrink chamber to shrink the landing gear. Moreover, the shrink pump and unshrink valve may be part of a strut shrink system.
