Vehicular hydraulic system with priority valve |
摘要 |
A vehicular hydraulic system with a pump and first and second hydraulic applications arranged in series. A valve is disposed whereby fluid from the pump flows through an inlet port, primary flow channel and outlet port of the valve to the first hydraulic application. The valve includes a body and a valve member that axially slides within an elongate valve chamber, partitioning the primary flow channel from a low pressure volume. The valve also includes a low pressure port and a bypass port. The bypass port is sealed from fluid communication with the valve chamber in a first position and is in fluid communication with the primary flow channel when the valve member is biased into a second position by a threshold exceeding elevated fluid pressure in the primary flow channel. Fluid discharged from the bypass port is diverted past the first application to the second application.
