Abstract
A dual action hydraulic piston assembly including a cylinder having first and second inlet ports on a first end and an outlet port on a second end, a conduit connected to the first inlet port and extending into the cylinder, an inner ram slidable along an outer surface of the conduit, and an outer ram slidable between the inner ram and the cylinder. The inner and outer rams are configured to move together toward the second end of the cylinder in response to a fluid being displaced via the first inlet port into the conduit, which displaces a second fluid through the outlet port at a first flow rate. The outer ram is configured to move toward the second end of the cylinder in response to a fluid being displaced via the second inlet port, which displaces the second fluid through the outlet port at a second flow rate.
