摘要： A coupling system for receiving a push rod includes a housing defining an internal channel having a sloped wall, and a piston received within the internal channel. The piston includes at least one flexible member arranged within the channel to be acted upon by the sloped wall to engage the push rod. The only external force required to couple the push rod is an axial force on the piston in a direction. The only external force required to de-couple the push rod is an axial force on the piston in an opposite direction.

摘要： A reservoir (26) includes first and second chambers (38, 36), and a piston (42) having first and second ends (48, 44) disposed in the first and second chambers (38, 36), respectively. The first and second ends (48, 44) isolate a first area (52, 112) from a second area (50, 46) within the first and second chambers (38, 36). The first area (52) of the first chamber (38) is in fluid communication with a high pressure fluid source and the second area (50) of the first chamber (38) is in fluid communication with a low pressure fluid source. An orifice (56) is formed in the first end (48) and is configured to allow fluid communication between the first and second areas (52, 50) of the first chamber (38). A pumping system (10) and an aircraft are also disclosed.

摘要： The present invention relates to a fuel injection pump having a variable pressure chamber which can adjust a fuel injection timing according to each engine load with a simple structure and a lower manufacture cost compared to the conventional injection pump without a separate apparatus for moving a barrel as well as not modifying a shape of a plunger. The fuel injection pump having the variable pressure chamber further includes a pressure adjustment means including a contact plug of which lower portion is inserted and installed in the upper cover; a cylinder of which lower portion is inserted and installed in the contact plug and having the variable pressure chamber formed inside thereof; a main fuel pressing hole formed in the upper cover and the barrel to connect the variable pressure chamber of the cylinder and a plunger insertion hole of the barrel; a piston installed in the variable pressure chamber of the cylinder to enable an upward and downward sliding motion thereof; and a manual pressure adjustment unit installed on an upper portion of the cylinder to enable a vertical height adjustment to elastically support the upper portion of the piston.

摘要： A hydraulic pump radiant noise reduction method for a forklift or other work machine is disclosed. The method includes initiating a noise control algorithm that is enabled during periods when the displacement of the hydraulic pump remains in the zero displacement position and an operator is not demanding flow from any of the hydraulic branch circuits. When the noise control algorithm is enabled, the control valve assembly associated with the hydraulic branch circuit having the lowest hydraulic fluid pressure in relation to the hydraulic fluid pressures of all other hydraulic branch circuits is opened while the remaining control valve assemblies are in held or placed in a closed position. In an alternative embodiment, a drain valve assembly is provided that is opened when the noise control algorithm is activated.

摘要： [Problem] To provide a hydraulic working machine capable of recovering, as electric power, energy to be used to increase a load on an engine upon burning particulate matter in exhaust gas.
[Solution] An exhaust gas temperature raising processing means, which increases a load acting on an engine (2) to raise a temperature of exhaust gas, includes an electric assist motor (5) connected to the engine (2) and an inverter (20) for adjusting a torque of the electric assist motor (5), and also includes a main controller (15) having a first determination means for determining whether or not an actuator control valve (8) is in a non-feed state and a second determination means for determining whether or not clogging has occurred on a filter of an exhaust gas purification system (17). When the non-feed state is determined by the first determination means and clogging is determined to have occurred on the filter by the second determination means, the main controller (15) drives the electric assist motor (5) to generate electric power such that a load acting on the engine (2) is increased.

摘要： The invention relates to a hydraulic system comprising a source of high pressure (A), a consumer (C) connectable to the source of high pressure (A) via a flow control valve (21), and a solenoid valve (22) arranged to control the flow control valve (21). The hydraulic system further comprises a hydraulic pilot valve (31) selectively controllable by the solenoid valve (22) to connect a control chamber (28) in the flow control valve (21) either to the source of high pressure (A) or to a low pressure side (T). When the solenoid valve (22) is actuated, the consumer (C) is pre-pressurized via a by-pass conduit prior to the opening of the flow control valve (21). At the same time, the source of high pressure (A) is arranged to act on a first and a second end (32, 33) of the hydraulic pilot valve (31) wherein a spring (36) is arranged to displace the hydraulic pilot valve (31) and connect the control chamber (28) to the low pressure side (T) to open the flow control valve (21).
