摘要： A linear compressor and a method of producing the linear compressor which do not generate eddy currents in an inside stator of a linear motor thereof, thus preventing an eddy current loss, caused by an electrical contact between a plurality of thin metal sheets of the inside stator. The linear compressor includes a cylinder having a piston therein, a magnet arranged around the cylinder to actuate the piston, and the inside stator arranged around the cylinder to be placed inside the magnet. The inside stator has the thin metal sheets arranged in a cylindrical arrangement, and a holder which is made of a nonconductive resin material and to which the thin metal sheets are insert-molded to be held in positions thereof in the cylindrical arrangement. Due to the nonconductive holder, the thin metal sheets are prevented from being in electrical contact with each other, and the linear compressor does not generate any eddy currents in the inside stator, and prevents an eddy current loss.

摘要： Pumping cartridges useful for medical and surgical pumping and infusion procedures are disclosed. Methods for manufacturing and utilizing such pumping cartridges and methods for pumping or infusing liquids for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment are also described. The invention includes, in one aspect, a series of pumping cartridges comprising cylinders and pistons constructed and arranged for sliding or reciprocating motion within the cylinders. The pistons and/or cylinders can comprise a sealing component including a circumferential, flared sealing flange and can be configured to enable the pumping cartridge to generate high liquid pumping pressures, for example above 1,000 psig. Many of the pumping cartridges disclosed can be relatively easily manufactured at a low cost per unit and can be configured to be detachable from a pump drive unit and disposable after a single use. Various compact flow path configurations are provided in the several pumping cartridge embodiments described, including a Y-shaped configuration, a T-shaped configuration, and an axial configuration. Some pumping cartridges disclosed include pistons including or at least partially forming a valve and/or pistons that are relatively movable with respect to a piston rod to which they are connected. Valve including a valve seat and a movable sealing element able to create a seal capable of withstanding differences in fluid pressures thereacross of at least about 1,000 psi, and in some cases up to in excess of 10,000 psi, without substantial fluid leakage therethrough are disclosed. In some of the disclosed valves, the movable sealing element is concave in shape, and can be curved, to create a mechanical advantage for improved sealing performance. Methods for manufacturing axially-configured pumping cartridges from thin-walled tubing are also disclosed, as well as a series of methods for pumping or infusing a liquid for delivery to the body of a patient or a surgical or medical instrument for performing a medical treatment using the above-mentioned pumping cartridges and devices.

摘要： An air compressor package having improved stability and portability. The air compressor package is positionable in an operational position, wherein the air compressor package is positioned on a base, and a transport position, wherein the air compressor package may be more readily transported. Positioning of the air compressor package into the transport position is accomplished by rotating the air compressor about a rotational axis that is generally parallel to the longitudinal axis of the air tank, which positions the air compressor in an orientation and position that is relatively comfortable, whether or not the air compressor is hand-transported.

摘要： A method for detecting compressor degradation includes the steps of providing a dataset for a compressor relating compressor operating parameters to each other; detecting real time actual values of the compressor operating parameters including an evaluated operating parameter; using at least one of the real time actual values and the dataset to determine a predicted value of the evaluated operating parameter; and comparing the predicted value of the evaluated operating parameter to the real time actual value of the evaluated operating parameter. This advantageously allows a prognosis of compressor performance to determine whether performance degradation is occurring.

摘要： The invention is a device and method in a high-pressure chromatography system, such as a supercritical fluid chromatography (SFC) system, that uses a pump as a pressure source for precision pumping of a compressible fluid. The preferred exemplary embodiment comprises a pressure regulation assembly installed downstream from a compressible fluid pump but prior to combining the compressible flow with a relatively incompressible modifier flow stream. The present invention allows the replacement of an high-grade SFC pump in the compressible fluid flow stream with an inexpensive and imprecise pump. The imprecise pump becomes capable of moving the compressible fluid flow stream in a precise flow rate and pattern. The assembly dampens the damaging effects of an imprecise pump, such as large pressure oscillations caused by flow ripples and noisy pressure signals that do not meet precise SFC pumping requirements.

摘要： A reciprocating pump includes a drive section and a pump section. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied by a reciprocating circuit during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. Depending upon the polarity of the control signals applied to the coil, the coil is driven in one of two directions of movement. The reciprocating circuit employs a storage capacitor and several switches to capture the energy of the reciprocating coil as the pump is driven downwardly. The charge is recycled as the capacitor dissipates, thereby reversing the polarity of the current through the coil and driving the coil assembly upwardly to its initial position. A drive member transfers movement of the coil to a pump element which reciprocates with the coil to draw fluid into a pump chamber and expel the fluid during each pump cycle. The pump is particularly well suited to cyclic pumping applications, such as fuel injection systems for internal combustion engines.

摘要翻译： 往复泵包括驱动部和泵部。 驱动部分具有往复式线圈组件，在运行期间由往复运动电路施加交替极性控制信号。 驱动部分的永磁体结构产生磁场，该磁通场与在将控制信号施加到线圈期间产生的电磁场相互作用。 根据施加到线圈的控制信号的极性，线圈在两个运动方向中的一个方向上被驱动。 当泵被向下驱动时，往复运动电路采用存储电容器和多个开关来捕获往复式线圈的能量。 当电容器消散时，电荷被再循环，从而使通过线圈的电流的极性反转，并将线圈组件向上驱动到其初始位置。 驱动构件将线圈的运动传递到与线圈往复运动的泵元件，以将流体引入泵室并在每个泵循环期间排出流体。 该泵特别适用于循环泵送应用，例如用于内燃机的燃料喷射系统。
