Systems, apparatus and methods that allow external infusion, IV or administration pumps to be synchronized with the internal pumps for a medical fluid therapy machine are provided. The system reduces the time and effort needed to calculate, set-up, enter and maintain flowrates of various fluids, maintained internally or externally with respect to the medical fluid therapy machine. The system also automatically follows therapy requirements, for example, a requirement that one pump / fluid be running / flowing for another pump / fluid to be enabled to run / flow. The system further automatically adjusts for variations in flowrate of one fluid with respect to another. In short, the system provides a more “hands-off”, safe and effective method and apparatus for medical fluid therapy fluid delivery.

The invention provides a jet engine, which is mainly characterized by consisting of an air inlet (1), a gas compressor (2), a combustion chamber (3), a tail nozzle (5) and an independent power plant (7), wherein a power output shaft (8) of the independent power plant (7) is connected with the compressor (2) and drives the gas compressor (2) to rotate to work. By adopting the independent power plant capable of independently changing the output power to replace a turbine in the prior art, the jet engine effectively reduces the pressure ratio of the gas compressor under the condition of same thrust, and avoids the problem of poor aerodynamic stability caused by the matched work of the gas compressor and the turbine; and the engine can better work under different loads, thereby simplifying a structure of the engine, avoiding the surge phenomenon of the gas compressor, and increasing the work scope and the reliability.

A pull-cord start system has a recoil pulley coupled to a crankshaft of a combustion engine and a pull-cord wound about the recoil pulley which is pulled by an end user to rotate the recoil pulley and thereby start the engine. A throttle override device of the pull-cord start system has a shuttle coupled to the pull-cord for movement from a biased rest position to an active position when the pull-cord is being pulled by an end user. A linkage of the throttle override device which is preferably a Bowden cable extends between a throttle control and a throttle valve of a carburetor and is associated with the shuttle so that actuation of the throttle control when the shuttle is in the active position will not open the throttle valve which preferably is biased to an idle position because movement of the shuttle to the active position produces slack in the linkage.

A pull-starter for a combustion engine of an engine-powered apparatus having a startup element automatically actuated upon initial pulling of a pull-cord. The pull-cord is attached to and wound around a recoil pulley, routed at least partially around a portion of a movable dampener member, and attached to a handle. The dampener member is biased toward a rest position and a portion thereof is linked to the startup element. The pull-cord is pulled to displace the dampener member away from its rest position, automatically actuate the at least one startup element, and unwind the pull-cord from around the recoil pulley and thereby rotate the recoil pulley in an unwind direction to rotate a crankshaft of the engine via a coupling. At least upon release of the pull-cord, the dampener member and the startup element automatically return to their normal state during engine operation.
