ABSTRACT:
In a hydrostatic transmission, an oil expansion reservoir is formed as an integral part of the hydrostatic transmission housing, providing an extension to the housing chamber which encloses motion transmitting components of the transmission. The reservoir is defined by a yieldably compressible hollow body mounted within the chamber of the transmission housing. The hollow body is sealably attached at its open end to the outer wall of the transmission housing. The body includes a continuous cylindrical sidewall connected to a closed end wall and formed of alternating reversed annular folds which cause compression and expansion of the body sidewall to occur in a bellows-like fashion rectilinearly along a central longitudinal axis of the body.
