    Abstract: A liquid pump of the present disclosure includes a container, a shaft, a bearing, a pump mechanism, a storage space, and a liquid supply passage. The shaft is disposed in the container. The bearing supports the shaft. The pump mechanism pumps a liquid by rotation of the shaft. The storage space is defined in the container at a position outside the pump mechanism. The storage space stores the liquid to be taken into the pump mechanism or the liquid to be discharged to outside of the container after being expelled from the pump mechanism. The liquid supply passage is a flow path including an inlet open to the storage space and supplying the liquid stored in the storage space to the bearing.

    Abstract: A pump is formed by a housing (10) having a fluid inlet (11) and a fluid outlet (12) and containing a rotor (15) forming with the housing (10) chambers (17a, 17b) that, on rotation of the rotor (15) by a drive, convey fluid from the inlet (11) to the outlet (12) to pump the fluid. A seal assembly (14) is arranged between the outlet (12) and the inlet (11). The seal assembly (14) includes a membrane (21) that contacts the rotor (15) and a flexible resilient spring member (22, 28, 35, 37, 40) that provides a force urging the membrane (21) against the rotor (15). The spring member (22, 28, 35, 37, 40) thus, on rotation of the rotor (15), moves radially relative to the axis of rotation of the rotor (15) and is arranged to provide a force on the rotor (15) via the membrane (21) that is constant and a minimum to maintain a seal between the rotor (15) and the seal (14) for a given outlet pressure of the pumped fluid.

    Abstract: A vane of a compressor which is manufactured by inserting fiber in resin or a metallic vane preform performs a linear reciprocating movement together with revolving rotation of a rolling piston being inserted in a vane slot of a cylinder (40) can prevent damage of the vane and parts which perform relative motion with the vane, improve reliability by reducing vibration noise, as abrasion resistance and vibration absorbency of the vane which divides a compression space (P) of the cylinder (40) into a suction region and a compression region are improved. Also, as the weight is lightened, the linear movement can be smoothly done and input power source can be reduced.

    Abstract: A capacity-variable rotary compressor, in which a vane can be restricted by a pressure difference generated between both side surfaces of the vane when the compressor performs a saving driving, and simultaneously be restricted rapidly and stably by rapidly decreasing a pressure of a vane chamber by leaking a discharge pressure of the vane chamber to an inlet via a low pressure passage and thereby increasing a pressurizing force applied to a side surface of the vane relatively greater than a supporting force applied to a rear surface thereof, whereby the vane can be previously prevented from being vibrated due to a weak restriction force of the vane when a power mode of the compressor is switched into the saving mode, which results in preventing of noise from being increased due to design conditions, thereby enhancing comfortable feeling.

    Abstract translation: 一种容积变化的旋转压缩机，其中，当压缩机进行节能驱动时，叶片能够在叶片的两个侧面之间产生的压差而受到限制，同时通过快速稳定地限制叶片室的压力 通过经由低压通道将叶片室的排出压力泄漏到入口，从而增加施加到叶片的侧表面的加压力相对大于施加到叶片的后表面的支撑力，由此叶片可以预先 当压缩机的动力模式切换到节能模式时，由于叶片的弱限制力而防止振动，从而防止由于设计条件而增加噪声，从而增强舒适感。
