Latest Patents
Harman's latest innovations include:
1. **Valve Spool with Flow Force Mitigation Features** - This inventive spool features a body that varies in diameter along its length, forming a series of lands with variable diameters. One of these lands is designed to control fluid flow from a workport passage to a return cavity. Additionally, it incorporates a multitude of axial grooves arranged in a circular pattern around the land’s circumference. The design includes a first and a second set of axial grooves, with the second set having a greater axial length, allowing for engagement with the return cavity before the first set.
2. **Hydraulic Control Valve Configured to Use a Pilot Signal as a Substitute Load-Sense Signal** - This valve assembly is designed to generate a valve load-sense pressure signal that reflects the pressure at a workport of an actuator. It also generates a pilot fluid signal that facilitates the shifting of a spool within the valve assembly's worksection. The invention includes a mechanism to compare the pressure levels of both signals, enabling fluid communication to a load-sense port when specific pressure conditions are met.
