    摘要: A hydraulic system is provided, the hydraulic system including a hydraulic load defining a first chamber and a second chamber. Additionally, the hydraulic system includes a pressure source, a fluid storage vessel, a load sense line, and a spool valve. The spool valve fluidly connects the fluid storage vessel to one of the first or second chambers and fluidly connects the pressure source to the other of the first or second chambers. A bypass line is also provided defining a flow path between the hydraulic load and the fluid storage vessel that bypasses the spool valve. Fluid flow may encounter less resistance through the bypass line, such that the hydraulic system may run more efficiently and with a reduced risk for cavitation in the hydraulic load.

    摘要: A hydraulic circuit for supplying fluid at a plurality of different pressures. The circuit comprises (a) a reservoir containing fluid at an upstream pressure level; (b) a pump for receiving a fluid from the reservoir and for raising the fluid pressure of the fluid from the upstream pressure level to a downstream pressure level; (c) a pressure conduit for receiving the fluid from the pump; (d) an adjustable relief valve for receiving fluid at the downstream pressure level from the pump; and, (e) remote control means for remotely adjusting the adjustable relief valve. The adjustable relief valve is (i) connected to a relief conduit and to the pressure conduit, (ii) operable to open to connect the pressure conduit with the relief conduit when the downstream pressure level exceeds an actuation pressure level, (iii) operable to close to isolate the pressure conduit from the relief conduit when the actuation pressure level exceeds or is equal to the downstream pressure level, and (iv) remotely adjustable to change the actuation pressure.

    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.
