It is preferable that power steering permits 'static park' and has a good 'road feel' when running. In order to permit 'static park', a large bore actuation cylinder with high flow pump is required. Such a method, however, has two defects, a loss power for driving a large volume pump and a poor 'road feel'. Resolving these problems and achieving the above matters, Hino has developed a load sensing power steering system. This system, which employes two actuation cylinders controlled by means of a unique load sensing valve arrangement, is designed to permit use of only one cylinder for highway speeds and both cylinders during a static park maneuver. When the system is combined with the preceding speed sensing power steering, 'static park' is further facilitated and a tasty 'road feel' is available in accordance with vehicle speed.
