摘要： A hydraulic device having a first shaft including a first rotor, and a second shaft including a second rotor, the first and second rotors being constructed by adjacently fitting the same shape rotor elements, respectively. The rotor elements have teeth on the outer periphery thereof at a constant interval, and each tooth has a tip portion fluid-tightly engaged with an inner wall of a housing of the device. The rotor elements are adjacently fitted to the shaft in such a manner that the rotor elements are displaced in the same rotational direction along the axial direction of the shaft. The teeth tip portions of the rotor elements adjacent to each other are overlapped so that spiral paths are defined on the outer surface of the rotor.

摘要： A multiple-turn scroll pump comprises a pumping unit on each lateral side of a base plate of an oscillatable scroll piston driven by an eccentric drive. Each pumping unit includes a spirally shaped groove in a scroll housing and a spirally shaped displacement blade forming part of the scroll piston. The groove in one of the pumping units extends from the peripheral part of the scroll housing through at least one turn of a spiral and terminates at the intermediate part of the housing. The groove in the other pumping unit also begins close to the peripheral part of the scroll housing but extends through a number of spiral turns greater than that of the groove in the first pumping unit. Passages are provided in the scroll piston to communicate grooves in both units in such a manner that the fluid drawn into the first pumping unit is compressed mainly in the second pumping unit and is discharged solely therefrom. Mechanism for constraining the movement of the oscillating piston with respect to the scroll housing is conveniently housed within the confinement of the groove in the first pumping unit to reduce the overall radial dimension of the pump.

摘要： A multiple-vane rotary compressor having a cylinder bore profile especially designed to reduce the fluctuation in the overall drive torque applied to the rotor shaft. The cylinder bore profile is configured and designed so that the individual drive torque applied to an individual vane during the compression and delivery strokes varies along a drive torque-vane angle curve which approximates an isosceles triangle having a lower side corresponding to a range of angle of 180.degree.. The cylinder bore profile includes, for a profile section extending through an angle of 180.degree., a first region (i) in which the amount of vane projection is held substantially constant at a maximum value (D), a second region (ii) in which the amount of vane projection decreases at a higher rate, and a third region (iii) in which the amount of vane projection decreases to zero at a lower rate, the imaginary transitional point (A.sub.3) between the second and third regions being located at an angular position of 90.degree..

摘要： A vane compressor capable of obtaining a two stage compression. The compressor has a front and rear rotor 6a and 6b for defining, together with a cylinder bores 43 and 44, first and second operating chambers 39 and 40, respectively. A refrigerant from a first inlet opening 28 is sucked into the first operating chamber 39 by a rotation of the front rotor 6a for obtaining a first stage compression at the first chamber 39. The refrigerant is then introduced, via an intermediate pressure chamber 36, to the second operating chamber 40 for obtaining a second stage compression at the second chamber 40, which is discharged outwardly.

摘要： A piston in a first cylinder is driven as a piezoelectric element group, which includes a plurality of laminar piezoelectric elements stacked in layers, extends or contracts. A second cylinder is formed so as to connect with a first fluid pressure chamber which is defined in the first cylinder by the piston. A piston-shaped valve member is disposed in the second cylinder. The valve member is urged toward the first fluid pressure chamber by a spring. The first fluid pressure chamber is supplied with a fluid whose pressure is set by means of a selector valve. When the selector valve is closed, the fluid pressure chamber is defined as an independent compartment. In this state, high voltage is applied to the piezoelectric element group to elongate it, thereby driving the piston. Thus, the valve member is actuated by the fluid pressure inside the first fluid pressure chamber, and a fluid passage is opened and closed by the valve member.
