VARIABLE DISPLACEMENT DEVICES AND RELATED METHODS

摘要

Variable displacement devices and related methods are provided that can be used to change the amount of volume displaced by pistons within corresponding cylinders. The subject matter disclosed herein can relate to variable displacement devices usable as pumps, combustion engines, air compressors, compressed air engines, hydraulic engines, or the like, that can be used to change the amount of volume displaced by pistons within corresponding cylinders while the compression ratio remains substantially constant or can be variable as well depending on the configuration of the variable displacement devices and their components.

1. A variable displacement device comprising:
a main shaft having a main shaft axis, the main shaft configured to be rotatable about the main shaft axis; a cylinder block having one or more cylinders therein; a wobbler carrier movably connected to and rotatable with the main shaft; a wobbler being operatively engaged by the wobbler carrier but the wobbler not being rotatable with the wobbler carrier and the main shaft as the main shaft rotates; a wobbler follower secured to the wobbler; one or more pistons corresponding to the one or more cylinders with each piston being movable within the corresponding cylinder, the one or more pistons being pivotably attached to the wobbler follower; and an adjustment assembly secured to the wobbler follower, the adjustment assembly configured to be adjustable to change the angle of the wobbler carrier relative to the main shaft axis by the adjustment assembly moving the wobbler follower.
