摘要： A power supply feeds a dc voltage to an operational amplifier at an inverting input while a motor current command value is input to the operational amplifier at a non-inverting input and when a dc voltage being supplied to a power amplifier varies the operational amplifier responds to the voltage variation by adjusting the motor current command value to alter a control signal applied to a motor control circuit and thus reduce revolution-rate variation.

摘要： A shaft load balancing system includes a housing divided into a first chamber at a first operating pressure and a second chamber at a second, lower operating pressure. A shaft passes from the first chamber into the second chamber. The shaft includes a first end in the first chamber, a second end in the second chamber, and a substantially axial channel connecting the first end and the second end. The first end is in fluid communication with a fluid reservoir in the housing. A reaction member engages the second end. The reaction member includes a compression volume in fluid communication with the channel. A pressure differential between the chambers forces fluid from the fluid reservoir through the channel and into the compression volume. The reaction member transmits the fluid force to the housing, allowing the fluid to create a force on the second end of the shaft.

摘要： An internal housing is surrounded by an external housing, forming an external space. A total quantity of fuel, pumped by the fuel feed pump into the external housing is divided in such a manner into two subquantities of fuel such that the subquantity of fuel, required by a motor, flows out of the fuel feed pump after flowing through the external space and an internal pump housing space. The other subquantity of fuel flows to a pressure regulator without flowing through the external and internal spaces of the pump.

摘要： A power generating assembly structured to have dual functionality by combining an interactive operation of both an engine assembly and a compressor assembly in an at least partially segregated or isolated relation to one another within a common housing. The engine assembly may be connected to anyone of a plurality of different power take-offs in order that the power generated thereby is capable of doing work. Concurrently the compressor assembly is operative to pressurize a fluid flow passing there through and more specifically to increase the pressure of a refrigerant vapor which, after compression is transfer to a condenser or other utilitarian device for operation of a space conditioning or like facility. Interaction between the engine assembly and the compressor assembly is primarily attributable to the workings of a piston assembly comprising at least one but preferably a plurality of free moving pistons, wherein cyclical operation of the piston assembly defines a sequence of alternate compression and expansion phases of both the engine assembly and the compressor assembly.

摘要： An inline type pump in which a rotor having an axial flow vane is arranged inside the cylindrical stator. The fluid is discharged from the discharging port after a rotating kinetic energy of the fluid transferred by the axial flow vane toward the discharging port is changed into a static pressure energy at the pressure chamber. With such an arrangement as above, it is possible to increase a fluid supplying efficiency after satisfying a small-sized structure and further it is possible to increase an output of the pump as well as its efficiency.

摘要： An engine type apparatus converts the energy released by the internal combustion of a hydrocarbon fuel directly into high pressure. A power cylinder is physically located opposite one of a gas or liquid work cylinder. The power piston is coupled directly to either the gas/liquid work piston. Gas/liquid, under low pressure, enters the work cylinder to cause the coupled pistons to move and generate the compression stroke. The ignition of compressed fuel and air forces the coupled pistons in the opposite direction and the trapped gas/liquid travels through a one-way valve into one or more high-pressure accumulator(s). The pressure of the gas/liquid drives a pneumatic/hydraulic motor to accomplish work. The process is controlled by load requirements to create an “energy on demand” system.

摘要： A heat dissipation fan has a casing, a stator, a lubricating bushing and a fan. The stator is secured to the casing with a sleeve. The lubricating bushing has lubricant contained therein and is mounted in the sleeve. The fan is rotatably mounted in the casing and has a permanent magnet to be a rotor. A shaft extends from the fan and through a passage defined through the lubricating bushing. A locking disk is securely mounted on the shaft to hold the lubricating bushing. An oil guide is arranged on the lubricating bushing. Accordingly, the air in the cavity can be released from the oil guide during the assembly of the dissipation fan. The oil guide can keep oil from flowing out of the sleeve and drying out the lubricating bushing. The useful life of the dissipation fan is prolonged.
