摘要： A nozzle needle of a fuel injector is driven in a controlled manner by changing back pressure applied thereto. The back pressure is controlled by a pressure control valve driven by stacked piezoelectric elements. A valve body of the pressure control valve is disposed in a valve chamber having a drain port and a high pressure port which are selectively closed. A diameter D1 of a drain seat, a diameter D2 of a high pressure seat, and a diameter D3 of a piston portion connected to the valve body are set to satisfy a relation: D1≧D2≧D3. In this manner, operation of the pressure control valve is stabilized, and thereby the fuel injector is smoothly and stably operated.

摘要： A regulator for controlling the pressure of flowing fluid and also for selectively fully enabling or stopping the flow. The regulator valve includes a valve housing having an inlet passage and an outlet passage connected by a flow passage with a seat surrounding the flow passage. A valve member is movable toward and away from contact with the seat. A control housing is attached to the valve housing. An elongated rod connected at one end to the valve member has an opposite end extending into the control housing. A rod piston is connected to the opposite end of the elongated rod and is movable in the control housing in sealing engagement with the walls thereof. A compression spring is provided to bias the rod piston and the valve member in directions either toward or away from sealing engagement with the flow passage seat. An auxiliary piston is positioned in the control housing on the side of the rod piston away from the seat. An extender is formed on the auxiliary piston and is engageable with the rod piston to maintain a minimum spacing between the rod piston and the auxiliary piston. Alternately a cup-shaped member with an extender could be on the rod piston. First and second ports and a vent port are formed in the control housing and can be alternately connected by conduits to deliver pressure to move the valve member toward or away from the valve seat. A solenoid operated control valve or similar device is positioned in the conduit leading from the inlet passage for controlling the flow of fluid in this conduit.

摘要： A unidirectional-retroaction electromagnetic valve comprises a valve body, O-ring, manual opening unit, and electrically controlled blocking unit. The valve body is connected to a gas source directly and the electrically controlled blocking unit is used to stop gas in a dangerous situation. Two actions are required to open the electromagnetic valve when the dangerous situation no longer exists. First, push the manual opening unit to move the valve plate of the electromagnetic valve forward a certain distance, then the electrically controlled blocking unit moves the valve plate further according to a danger removal signal provided by a judgment device. The electromagnetic valve is not opened completely until these two movements are operated, thereby, it can prevent the blocked valve from opening intentionally during an unsafe situation.

摘要： A pressure relief valve includes a housing having a passage formed therein for connection with a fluid source and a seal surface positioned about an opening in the passage. A valve member positioned within the housing is movable along an axis within the cavity to selectively engage the seal surface in a sealing relationship. The housing is sized and shaped to substantially restrict movement of the valve member to a direction parallel to the axis. A spring is coupled to the valve member to apply a spring force to the valve member to bias the valve member into contact with the seal surface. In operation, the valve member may separate from the seal surface upon application of a fluid pressure force on the valve member that is greater than the spring force thereby allowing pressurized fluid to pass through a discharge opening in the housing.

摘要： Disclosed is a pressure relief valve for attachment to a closed vessel having an opening to vent gas and liquids from the housing should the internal housing pressure rise to unacceptable levels. The pressure relief valve includes a single gasket that seals between a valve disk and a collar disposed about the opening. The gasket is fixed to the collar by a single retaining ring and effects seals with the disk valve in two planes, one seal is in a plane generally parallel to the plane of the opening and a second seal is in a plane generally normal to the plane of the opening. Moreover, the second seal remains in tact for a short time after the first seal is broken to permit the rapid separation of the disk valve from the gasket to vent gas and liquids from the housing.

摘要： A pressure release apparatus for relieving pressure that may occur within a pipeline due to water hammers or the like. This apparatus is secured to the pipeline directly in line with the pressure wave and consists of a spool piece having an opening therethrough which is selectively biased in the closed position. When pressure within the pipeline is sufficient to overcome this bias, the opening is unblocked thereby permitting such pressure to be released to the atmosphere. A blast shield surrounds this opening so that the sudden release of such pressure will not cause damage to surrounding people or property.
