摘要： A rotary cylinder type compressor includes: a cylinder that is rotatably placed in an inside of a housing; a rotor that is placed in an inside of the cylinder and is rotatable about an eccentric axis that is eccentric to a rotational central axis of the cylinder; and a partition member that partitions a working chamber formed between an outer peripheral surface of the rotor and an inner peripheral surface of the cylinder into a suction space and a compression space. When a pressure of fluid in the compression space is equal to or larger than a reference pressure, a contact stress, which is exerted at an adjoining portion between the outer peripheral surface of the rotor and the inner peripheral surface of the cylinder, is increased in comparison to a case where the pressure of the fluid in the compression space is smaller than the reference pressure.

摘要： A compressor according to the present invention includes an oil separation mechanism and an oil supply mechanism. The oil separation mechanism includes an oil separation chamber and an oil drain path. The oil supply mechanism includes an oil supply port. The oil drain path includes a first flow path formed by penetrating a second partition of a housing and configured to open toward a first partition of a housing from the oil separation chamber, and a second flow path recessed in at least one of the first partition and the second partition and formed by the cooperation of the first partition and the second partition so as to get communicated with the first flow path. An outlet of the second flow path is located at a higher level in a vertical direction than an inlet of the second flow path while avoiding a direction facing the oil supply port.

摘要： A rotating vane vacuum pump includes a housing defining a cavity having an inlet and an outlet, a drivable vane member for a rotary driven movement inside the cavity, a rotor inside the cavity, and a rotatable central shaft extending into the cavity. The vane member is coupled to the central shaft by an eccentric element on the central shaft and movably arranged in the rotor, the rotor being rotatable together with said vane member upon rotation of the vane member. A rotational axis of the central shaft is offset from a rotational axis of the rotor and a point of action of the vane member is offset from the rotational axis of the central shaft by the eccentric element on the central shaft. The rotor encloses radially the eccentric element of the central shaft.

摘要： HVAC systems and methods for delivering highly efficient heating and cooling using ambient air as the working fluid. A plenum has an upstream inlet and a downstream outlet, each in fluid communication with a target space to be heated or cooled. Ambient air is drawn into the inlet at an incoming pressure and an incoming temperature. The inlet and outlet are gated, respectively, by first and second rotary pumps. A heat exchanger in the plenum transfers heat into or out of the air, provoking a change in air volume within the plenum. Work is harvested in response to change in air volume. The systems and methods can be configured to replace a traditional blower fan used to circulate the interior and exterior air. The systems and methods can be configured to implement a technique referred to as Convergent Refrigeration.

摘要： A gap between a vane tip and a cylinder inner circumferential surface is denoted by δ. If rv is set as in an Expression (1), a first vane rotates with the vane tip thereof being out of contact with the cylinder inner circumferential surface. In the vane compressor, wear at the tip of a vane is suppressed, loss due to sliding on bearings is reduced by supporting a rotating shaft portion with a small diameter, and accuracy in an outside diameter and center of rotation of a rotor portion is increased.

摘要： A negative pressure pump includes an electrically insulative casing an electrically conductive rotary shaft and an electrically conductive vane. The casing is formed in a tubular shape, an axial direction one end of which is closed off by a cap body. The rotary shaft is disposed in the casing, is mechanically and electrically connected to an earthed power source, and is rotated by power being transmitted from the power source. The vane is disposed in the casing, is supported at the rotary shaft to freely reciprocate in a direction orthogonal to the rotary shaft, and is electrically connected to the power source via the rotary shaft. The vane rotates integrally with the rotary shaft, and end portions of the vane slide over an inner wall face of the casing. The vane divides the interior of the casing into a plurality of spaces and generates negative pressure.
