    摘要： A pumping device includes a main body having a passage defined therein through which air passes, a head connected to the main body, and a retainer slidably received in the head. The retainer includes a first compartment communicated with the passage. The second end of the retainer includes a conical recess defined therein, and a nozzle is slidably mounted in the second end of the retainer. A nozzle head is securely mounted in the second end of the head and includes a second compartment communicated with the first compartment via the nozzle. The nozzle head includes a hollow conical section for engaging with the conical recess of the retainer. A retaining pin is mounted in the first compartment and has a first end secured to the first end of the nozzle to slide therewith. A lever includes a first end pivotally connected to the first end of the head and a second operative end for switching the first end of the retaining pin and the retainer between a first operative position in which the first end of the lever bears against the first end of the retainer and the first end of the retaining pin and a second inoperative position in which the first end of the lever neither engages with the first end of the retainer nor engages with the first end of the retaining pin.

    摘要： An adjustment valve is provided with a system able to prevent its piston from jamming. This piston (30) is fitted with a vane wheel (50) placed at its end and receiving a flow of air under pressure. The piston is thus in constant rotation inside the body (20) of the valve. Application is for the injection of fuels in turbojet engines.

    摘要： A valve rotating device has an annular main body, an annular cover body, and an annular axial spring element. The main body has multiple pockets of variable depth so that raceways are formed for balls situated therein, wherein tangential springs press the balls against ends of the pockets in the circumferential direction. The cover body is rotatable relative to the main body about an axis and is axially displaceable, and has an annular first support element, an annular second support element, and a connection, wherein the support elements are axially spaced apart from one another and the connection connects the support elements so that they are fixed relative to one another. The axial spring element at a first end rests on an annular stop surface of the main body, and at a second end rests on a surface of the first support element, wherein the axial spring element is situated between the first support element and the second support element. A surface of the second support element facing away from the axial spring element rests against the balls, and the balls and the axial spring element are arranged in an overlapping manner in the radial direction.

    摘要： An improved, motorized Lunkenheimer valve is provided having two independently actuated drive means for operating the valve, one of which moves the valve stem and disc longitudinally along the axis of the stem and the other of which rotates the stem and disc about the longitudinal axis of the stem. The two drive means can be operated concurrently to effect more rapid opening or closing, and countercurrently to provide a continuous grinding operation when the valve is in the closed position.

    摘要： A control valve assembly for controlling hydraulic pressure comprising a non-adjustable unloader valve for large escape flow connected in parallel with a small adjustable trigger valve. The trigger valve opens when the pressure rises to an adjustable predetermined valve and exposes to this pressure on actuating piston of the unloader valve which is thereby opened. Means are disclosed for adjusting the closing characteristics of the unloader valve.
