摘要： A fluid pressure intensifier in which a body has a side wall and first and second end walls. A tube extends inwardly in the body from the first end wall and a piston head is slidably disposed on the tube. A cylindrical element in spaced relation to the body side wall extends from the piston head toward the second end wall. A fluid inlet in the second end wall supplies pressurized fluid to move the piston head on the tube. A fluid outlet through the tube transfers pressurized fluid from within the element out of the intensifier. The amount of pressure intensification is proportional to the surface area differential of the piston head and a cross section of the element.

摘要： 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.Internal Fluid Communication System for Power Cylinders
