摘要： In a scroll compressor, a stationary scroll is pressed toward a movable scroll by a back pressure of a discharge fluid compressed by a compression mechanism, and wear powder, produced from an annular seal (which receives the pressure of the discharge fluid) as a result of precession of the stationary scroll, is arrested, thereby achieving the scroll compressor high in efficiency and reliability. A pressure-receiving surface for receiving a back pressure of the discharge fluid so as to press the stationary scroll toward the movable scroll is formed on that portion of the stationary scroll disposed around a communication port which is formed in the stationary scroll, and communicates with a discharge port. An annular seal is provided to form a seal between the stationary scroll and an upper frame around a region of communication between the communication port and the discharge port in such a manner as to satisfy a necessary annular sealing surface area, and a circumferential recess is provided on that side lower in pressure than this annular seal.

摘要： A scroll compressor employs therein a refrigerant having a small global warming potential and a small ozone depletion potential and mainly comprising hydrofluoroolefin having a carbon-carbon double bond. A stationary scroll has and end plate and a discharge port defined in the end plate at a central portion thereof so as to open into a discharge chamber. The stationary scroll also has a bypass hole defined in the end plate to allow a plurality of compression chambers to communicate with the discharge chamber before the compression chambers communicate with the discharge port. A check valve is provided on the bypass hole to allow the refrigerant to flow from the compression chambers to the discharge chamber. This construction can restrain a baneful influence on the global environment, reduce a temperature increase caused by excessive compression, and restrain decomposition of the refrigerant even in long-term use.

摘要： A hydraulic driving system includes a hydraulic cylinder with a cylinder tube and a cylinder rod, a main pump, a hydraulic-fluid path, a charge pump, a stroke position detecting unit, and a pump control unit. The hydraulic-fluid path forms a closed circuit between a main pump and the hydraulic cylinder. The cylinder rod expands or contracts depending on how hydraulic fluid is supplied and exhausted to and from first and second chambers. The charge pump replenishes hydraulic-fluid in the hydraulic-fluid path. The pump control unit performs flow-rate reduction control in which the pump control unit reduces a suction flow rate so that a suction flow rate of the main pump is equal to or less than a maximum discharge flow rate of the charge pump when the stroke position becomes closer to a stroke end of the cylinder rod than a prescribed reference position during the flow rate reduction control.

摘要： In a hydraulic excavator, a hydraulic cylinder drives a boom via a hydraulic fluid discharged from a first hydraulic pump. A first hydraulic circuit connects the first hydraulic pump and the hydraulic cylinder and forms a closed circuit therebetween. A hydraulic motor rotates a revolving upper unit with hydraulic fluid discharged from a second hydraulic pump. A second hydraulic circuit independent from the first hydraulic circuit connects the second hydraulic pump and the hydraulic motor. A motor hydraulic pressure reduction unit reduces the driving hydraulic pressure of the hydraulic motor when a predetermined condition is satisfied. The predetermined condition is a condition in which an operation of the boom operating member to raise the boom and an operation of the rotation operating member to rotate the revolving upper unit are conducted together and an operation amount of the boom operating member is equal to or greater than a predetermined threshold.
