摘要： PROBLEM TO BE SOLVED: To provide a flow rate control valve of a constant flow rate control type having a simple structure. SOLUTION: This flow rate control valve is provided with a constant pressure difference valve for controlling difference in pressure before and after the pressure loss caused by letting refrigerant pass in the evaporator 1 which is regarded as a restriction passage to a substantially constant value. The fixed pressure difference valve receives outlet pressure Px of the flow rate control valve in the direction of valve closing in its valve element 12 and receives outlet pressure Pe of the evaporator 1 in the direction of valve opening by a piston 13 to control in such a way that difference in pressure between inlet pressure and the outlet pressure Pe of the evaporator 1 becomes substantially constant in order to control refrigerant fed into the evaporator 1 to a constant flow rate determined by a current carried by a solenoid. Consequently, there is no necessity for providing the restriction passage in the flow rate control valve, a configuration of the flow rate control valve can be simplified, and the flow rate control valve with a low cost is provided.

摘要： PURPOSE: To atomize fuel in a good efficiency with a simple structure, and improve combustibility by arranging means for compressing air corresponding to rotation of a crankshaft, and supplying compressed air to a fuel injection mechanism in a relation of a time which is beforehand selected with respect to rotation of the crankshaft. CONSTITUTION: In a device wherein each of fuel injection mechanisms 31 are arranged on six cylinder 19 arranged on an engine block 13 in an internal combustion engine 11, compressed air is supplied to the fuel injection mechanisms 31 through a duct 45 connected to a valve body. A base plate 101 wherein a plurality of air compression cylinders 81 are arranged at equal angle clearance corresponding to each cylinder 19, is arranged on one end of an engine block 13, and a piston 83 is fitted into each cylinder 81 freely to be capable of reciprocating motion. The other end side of a connecting rod 121 connected to each piston 83 is pivotally fitted to an eccentrically driving hub 141 fitted to a crankshaft 15, compressed air is generated in order in each cylinder 81 in association with rotation of the crankshaft 15, and the compressed air is supplied to a duct 45.

摘要： An apparatus for delivery of fluids to a patient includes an inlet tube (102) and an outlet tube (104) connected to each other at an angular joint. A rotary valve (108) and a piston (122) are fitted to the angular joint forming a chamber (120). The rotary valve (108) is provided with a wedge shaped opening (112) and a priming tubule (114). For priming operation with the fluid delivery apparatus, a user sets the rotary valve to a priming position. During pumping operation, the rotary valve rotates in coordination with the piston (122) to transfer a quantum of fluid from the inlet tube (102) to the outlet tube (104) via the chambe (120)r. A second piston (402) is provided on the outlet tube (104) for smoothing out flow rate pulsations.

摘要： A crankshaft 15 rotatably mounted in the engine block 13 includes a cylindrical surface 131 in eccentric rotation to the crankshaft axis 17 and a plurality of compressor cylinders 81 are supported by the engine block. Pistons (83, Fig. 2) in the cylinders 51 each include an air inlet valve (151) and the cylinders each have an outlet valve (153). Air or fuel/air mixture produced by fuel injection into a chamber (213, Figs. 5 and 6), supplied with air, is supplied from the cylinders 61 to respective engine cylinder injectors (31, Figs. 1 and 6). The cylinder injectors may be supplied with fuel by solenoid injectors (37, Fig. 6). The member 101, 102 supporting the cylinders 61 may be angularly adjusted relative to the block 13. … …
