Hydraulic flowpath through a cylinder wall

Abstract:

Various embodiments of a hydraulic cylinder assembly, cylinder liner member and a hydraulic manifold for use with the hydraulic cylinder assembly reduce the need for external plumbing from the rear of the hydraulic cylinder assembly to the front of the hydraulic cylinder assembly. The cylinder liner member may include three bores that convey fluid from the manifold from the rear of the hydraulic cylinder assembly to the front of the assembly, conveying fluid to the retract volume of the cylinder.
