摘要： The present invention relates broadly to a flow diverter disposed in a plenum area of a motor cylinder chamber (also referred to as kidney ports). The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber. In addition, the flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool. The flow diverter allows for numerous options of where the main inlet to the motor can be positioned and provides a means of regulating the air or fluid flowing into the cylinder chamber.

摘要： A gas passage switching structure for a pneumatic rotary hand tool includes a pneumatic motor and a revolving valve disposed in a device case. The pneumatic motor has an input ending surface. A forward gas inlet and a reverse gas inlet are formed and spaced apart on the input ending surface. The revolving valve has a gas supply surface. A gas supply port and a discharge port are formed and spaced apart on the gas supply surface. The gas supply surface and the input ending surface are arranged along an axis line in the device case adjacent or in contact with the arrangement so that it allows the pneumatic motor to drive the forward and reverse rotation by the high pressure air flow along the fluid passage in the axis line direction.

摘要： An improved vane pump assembly is provided. The vane pump assembly includes a housing with an open chamber that is circular in shape when viewed in cross-section and has an inner wall that surrounds the open chamber. A rotor is rotatably disposed in the open chamber of the housing. As with the open chamber, the rotor is circular in shape when viewed in cross-section and has a diameter. The rotor further has at least one through-passage which extends diametrically across the rotor. The rotor is positioned such that it has a center that is offset from a center of the circular open chamber of the housing.

摘要： An expander-compressor unit (10) includes a two-stage rotary expansion mechanism (3) having a first cylinder (41) and a second cylinder (42). In the expansion mechanism (3), a suction port (71) facing a working chamber on the upstream side in the first cylinder (41) and a discharge port facing a working chamber on the downstream side in the second cylinder (42) are formed. An intermediate plate (43) is provided between the first cylinder (41) and the second cylinder (42). In the intermediate plate (43), a communication passage (43a) for allowing communication between a working chamber on the downstream side in the first cylinder (41) and a working chamber on the upstream side in the second cylinder (42) is formed. The communication passage (43a) does not communicate with the working chamber in the first cylinder (41) during the suction process, and communicates with the downstream working chamber in the first cylinder (41) at or after the end of the suction process.

摘要： To enhance evacuation of a storage bag having a one-way valve element and to reduce noise during evacuation, a handheld evacuation device includes one or more gaskets that can be made of resilient material. A gasket can be disposed about the rim of an inlet opening of the evacuation device to provide both a leak-free interface between the evacuation device and the storage bag and to reduce vibration and chatter of the evacuation device against a rigid support surface. A gasket can also be provided intermediately between a main body portion of the evacuation device and a nozzle portion that is to be placed adjacent to the storage bag during use. The intermediate gasket isolates vibrations in the main body portion thereby reducing vibrations and chatter of the evacuation device against a rigid support surface.

摘要： A rotary engine and a hydraulic motor including non-rotary outer and inner casings; a power shaft with an eccentric part; a driving eccentric ring between the outer and inner casings and mounted on the eccentric part; a combustion or pressure chamber between the eccentric ring and the inner casing such that the eccentric ring drives the power shaft by substantially non-rotating eccentric movement; dividers for dividing the combustion chamber into at least two parts, the dividers extend through the inner casing and are in contact with an inner surface of the driving eccentric ring; and an eccentric device (or control) for driving the dividers back and forth with respect to the inner casing. The eccentricity of the eccentric device corresponds with the eccentricity of the eccentric part of the power shaft. The eccentric device has a guide groove which implements an eccentric path and to which the dividers are connected.
