    摘要： The dunnage airbag inflation circuit of this invention includes a pilot valve that is controlled by a pressure sensing line in communication with the dunnage bag, and an arrangement of other valves to allow the dunnage bag to inflate up to a certain preset pressure. The pressure sensing line controls pilot air to various valves and ultimately to the main pilot valve allowing airflow to the dunnage bag until the dunnage bag reaches a certain preset pressure. The inflation circuit also includes (i) a safety pressure valve to stop airflow to the dunnage bag if for some reason the dunnage bag continues to be inflated past the preset pressure, and (ii) a stop valve that allows an operator to manually override the pressure valve and stop the airflow to the dunnage bag.

    摘要： Disclosed is a hydraulic circuit for an option device of heavy construction equipment which can facilitate manipulation of the option device such as a breaker and optionally control a flow rate by supplying hydraulic fluid from a hydraulic pump to the option device at a constant flow rate, regardless of the size of load produced on the option device.

    摘要： A hydraulic device comprises a variable displacement pump, a plurality of hydraulic actuators, a plurality of directional valves capable of controlling the delivery oil flowing into each of the actuators, a plurality of pressure compensation valves which compensate the pressures of respective directional valves, and a delivery oil flow rate varying means capable of controlling the pump delivery. At least one of the pressure compensation valves decreases its output flow to a particular actuator according to an increase in the loaded pressure of the particular actuator. With this arrangement, if the loaded pressure of the particular actuator suddenly changes, the loaded pressure attenuates to ensure stable operation of the hydraulic device. Further, the stable operation is fee of hunting for both low-load actuators and high load actuators, regardless of an independent operation or a compound operation.

    摘要： Fluid systems having fluid motors which control aiding type loads many times have problems with cavitation in one end of the fluid type motor during lowering thereof. It is desirable to eliminate all cavitation in the fluid motor during operation. In order to eliminate cavitation during lowering of an aiding type load and to provide a positive pressure therein, the subject arrangement provides an exhaust pressurizing control for use in a fluid system. The exhaust pressurizing control includes an exhaust manifold means having selector means to provide a positive pressure in the exhaust manifold means during lowering of an aiding type load. The selector means includes pressure limiting and unloading means operative to provide a positive pressure in the exhaust manifold means during lowering of the aiding type load and to unload the pressurized fluid in the exhaust manifold means during raising of a resisting type load. The pressurized fluid in the exhaust manifold means is available to the fluid motor through anti-cavitational valve means. This arrangement effectively eliminates cavitation in the fluid motor.
