摘要： An adjustable chair includes a base, a back and a chair control for pivotally connecting the back to the base for movement between a fully upright position and an inclined position. A cable actuated variable back stop mechanism includes a generally U-shaped bail or stop lever pivoted to the back. The bail is engageable with a stop on the chair base. A lock member is slideably mounted on the back. The lock member includes a front face defining a plurality of vertically spaced, generally parallel grooves. The grooves are dimensioned to receive the bail and hold the bail in one of a plurality of selected positions when the lock member is moved from an inoperative to an operative position. When in the operative position, the lock member prevents pivoting of the bail when it engages the stop on the base, hence, limiting tilting of the chair back.

摘要： Pumps and injectors having a control valve with an adjustable stroke for rate shaping and associated methods for operating a control valve are provided. The pump or injector comprises a body with a pumping chamber and a control valve chamber. A plunger is disposed in the pumping chamber. An actuatable control valve disposed in the control valve chamber controls fuel. The control valve includes a valve body moveable over an adjustable stroke range including opened and closed positions. The stroke range is adjustable to vary an effective open gap when the valve body is in the open position. An actuatable valve stop assembly adjacent to the control valve chamber includes a main body and a stop member that is moveable between extended and retracted positions. The stop member limits the stroke range such that the control valve has a first effective open gap when the stop member is in the extended position, and such that the control valve has a second effective open gap when the stop member is in the retracted position. A first armature and first stator assembly operate to actuate the control valve. A second armature and second stator assembly operate to actuate the valve stop assembly.

摘要： A fuel injector pump in a direct-injection fuel delivery system for an internal combustion engine including a solenoid valve for controlling transfer of fluid from a high pressure chamber to a fuel injector nozzle. A supply passage and a return passage provide a fuel flow circuit for the fuel delivery system, the high pressure chamber being defined in part by a camshaft-driven plunger. An independent fuel leak flow path is provided to accommodate fuel leakage past a plunger of the pump, the fuel leak flow path extending to a zero pressure fuel tank.

摘要： A pumping system for a fuel injection system includes a body defining a high pressure pumping chamber, a plunger, a high pressure outlet, a high pressure fluid line connecting the pumping chamber to the outlet, a control valve along the fluid line, and a valve and restriction arrangement along the fluid line. The valve and restriction arrangement includes a restriction and a valve body. The valve body is movable between an open position in which fuel flow from the pumping chamber is generally unrestricted by the restriction and a closed position in which fuel flow from the pumping chamber is significantly restricted by the restriction to store energy in the pumping chamber. Advantageously, the high pressure restriction concept may be utilized in a pumping system for various types of rate shaping, including boot injection and square injection, in addition to pilot operation and post injection operations, and others.

摘要： Pumps and injectors having a control valve spring arrangement configured to provide a force step when the control valve is at a rate shape position, and related methods for operating a control valve, are provided. The control valve is moveable over a stroke range between an open position and a closed position. The stroke range includes a rate shape position. The control valve spring arrangement is configured to provide a first spring force when the control valve is between the closed position and the rate shape position, and to provide a second spring force that is less than the first spring force when the control valve is between the rate shape position and the open position.

摘要： Pumps and injectors utilize a control valve having a valve body with a valve stem having a step adjacent to the seating surface. The step extends a limited distance away from the seating surface to provide limited pressure relief when the valve body is at an intermediate position that is between the opened and closed positions. Step cross-section and axial length may be configured based on desired hydraulic behavior. In a preferred embodiment, the control valve step is configured for injection rate shaping.
