    摘要： A blower housing including a first and second rotor assembly such that the first rotor assembly includes a first rotor and a first shaft and the second rotor assembly includes a second rotor and a second shaft. The first and second rotors each have a plurality of lobes. Each first and second rotor includes an axial sealing extension that can be constructed to extend axially into the shaft opening. The axial sealing extension can include a radially outwardly facing sealing surface that opposes a radially inwardly facing sealing surface defined within the shaft opening. The radially outwardly facing sealing surface and the radially inwardly facing sealing surface can be configured to cooperate to form a radial sealing interface that extends around an axis. The radial sealing interface can include a radial seal clearance defined between the radially outwardly facing sealing surface and the radially inwardly facing sealing surface.

    摘要： The invention relates to a rotary piston engine, comprising at least two working chambers which are formed by a housing, a working rotary piston which rotates therein and at least one rotating auxiliary rotary piston. The invention likewise relates to a method for operating said rotary piston engine. In order to make different compression ratios and ignition times possible and in order to increase the rotatability and tightness of the rotary pistons even during long-term operation of the rotary piston engine of the generic type, the rotary piston engine according to the invention comprises at least two working chambers which are formed by a housing, a working rotary piston which rotates therein and at least one rotating auxiliary rotary piston, wherein a working gas can be transferred via at least one duct from at least one of the working chambers into at least another one of the working chambers.

    摘要： A fluid-driven actuator system includes a fluid-driven actuator and at least one proportional control valve and at least one pump connected to the fluid-driven actuator to provide fluid to operate the fluid-driven actuator. The at least one pump includes at least one fluid driver having a prime mover and a fluid displacement assembly to be driven by the prime mover such that fluid is transferred from the pump inlet to the pump outlet. The fluid-driven actuator system also includes a controller that establishes at least one of a speed and a torque of the at least one prime mover to adjust at least one of a flow in the fluid system to a flow set point and a pressure in the fluid system to pressure set point and a concurrently establishes an opening of the at least one proportional control valve to adjust at least one of the flow to the flow set point and the pressure to the pressure set point.

    摘要： A multistage pneumatic motor includes a shell (1) and a power output main shaft (2). The shell (1) is provided with a gas inlet (3) and a gas outlet (4). Two or more pneumatic motor stages (11, 12, 13) are installed in the shell (1). The first pneumatic motor stage is communicated with the gas inlet (3), and the last pneumatic motor stage is communicated with the gas outlet (4). Compressed gas enters the shell (1) through the gas inlet (3), drives the first pneumatic motor stage, then drives the next pneumatic motor stage, and is exhausted from the shell (1) through the gas outlet (4) at last. Every pneumatic motor stage is provided with a power output shaft (112, 122, 132) which is connected to the power output main shaft (2), so that the powers produced by all pneumatic motor stages (11, 12, 13) are jointed together and then output by the power output main shaft (2). The multistage pneumatic motor improves working efficiency greatly, saves energy source and reduces noise.
