ABSTRACT:
An internal fluid communication system in combination with a fluid operated power cylinder, such as that used on industrial lift trucks, in which a pair of tubular sections in telescopic relationship is disposed lengthwise within the power cylinder, forming a fluid passageway through the cylinder for transmitting fluid from one end of the cylinder to the other. The cylinder may be of either the ram or the cylinder and piston type. Two or more tubular sections may surround the first tubular section and form a plurality of parallel fluid passages passing through the power cylinder from one end to the other without communicating with the operating fluid in the cylinder. In the embodiment of the invention applicable to a cylinder and piston type hydraulic motor, one tubular section is disposed in the piston rod and the other tubular section passes through the piston and is in telescopic relationship with the tubular section in the piston rod. While the present internal fluid communication system is particularly adapted for industrial lift trucks, it may be used in a variety of different types of applications on different types of equipment and machinery.
