摘要： An intermittent air discharge apparatus has a main valve and a pilot valve, the main valve being switched between a discharge state and a discharge stop state. The pilot valve is switched between an air-supply state to supply air to a pilot chamber for air-discharge, and an air-supply stop state. When the pilot valve is switched to the air-supply state, an exhaust passage communicates with the pilot chamber for air-discharge. When the pilot valve is switched to the air-supply state, a supply or exhaust passage allows an air supply passage to communicate with the pilot chamber for air-discharge and a pilot chamber for stopping air-supply; when the pilot valve is switched to the air-supply stop state, communication with the air supply passage is blocked. A flow rate of air from the pilot chamber for air-discharge is set by the exhaust passage, and a flow rate of air from the pilot chamber for stopping air-supply is set by the supply or exhaust passage.

摘要： A flow regulating valve subassembly includes a main valve configured as a seat valve and a valve piston. The valve piston is acted upon via a first end face by the pressure of a first working connection and via an annular surface of the valve piston by the pressure of a second working connection in the opening direction. The valve piston is also acted upon in the closing direction via a second end face by the pressure of the higher-pressure working connection. An adjustable throttle is formed between a housing of the main valve and the valve piston. The throttle has a cross section that changes continuously during displacement of the valve piston and connects the higher-pressure working connection to the second end face. A pilot control valve arrangement is configured to control a control line which connects the second end face to the lower-pressure working connection.

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).

摘要： A hydraulic spool valve includes a housing, a valve element disposed within the housing, a first piston coupled to the valve element, and a first biasing member. The housing includes a pair of first ports. The valve element is selectively moveable within the housing between a first closed position and a second open position allowing fluid communication between the first ports. Hydraulic pressure against the first piston causes helical translation of the piston in a first direction, and motion of the valve element in a first direction from the first position toward the second position. The first biasing member is configured to bias the first piston and the valve element toward the first position.
