    Abstract: PURPOSE:To make the operating reaction of a slider smaller so as to the size of the title valve smaller by forming the first and second valve seats in parallel to a valve body and accommodating the slider being slidingly touched onto both valve seats at both ends of a tunnel like passage of a holder. CONSTITUTION:There are formed the first valve seat 16c having a suction port 16e connected to the discharged side of a compressor 101, and the second valve seat 16d having the first and second introducing ports 16g, 16f connected to outside and inside heat exchangers 102, 103, on a valve main body 16. There is formed a discharge port 16a connected to the suction side of the compressor 101 on the side surface of the valve main body 16. Between both valve seats 16c, 16d, there is arranged a holder 26 for holding sliders 22, 23. This makes the pressure applied on the slider and operating reaction smaller, so that it is possible to directly drive the holder 26 with the plunger 30, thereby making the size of the valve smaller.

    Abstract: PURPOSE: To generate a flow of a refrigerant electromagnetically at a low noise accompanying no mechanical vibration by a method wherein a pair of electrodes is located in refrigerant piping corresponding to a superconductive coil arranged in proximity to refrigerant piping and a DC power source is connected to the electrodes to form a fluid pump. CONSTITUTION: Refrigerant in refrigerant piping 8a of a fluid pump 9 part is ionized by positive and negative electrodes 12. A Rorentz force is generated by a current flowing between the pair of electrodes 12 and 13 and a magnetic flex flowing between a pair of superconductive coils 10 and 11 and moves the refrigerant ionized in the direction of a condenser 2 to be circulated through a cooler in which the condenser 2, an expansion valve 3 and an evaporator 4 are connected in a ring. Thus, a flow of the refrigerant is generated electromagnetically by the Rorentz force in the fluid pump 9 to produce a flow of the refrigerant by a continuous fixed force accompanying no mechanical vibration thereby preventing the generation of vibration and noises in a refrigerant piping system with no pressure pulsation of the refrigerant.

    Abstract: PURPOSE:To reduce pressure loss under warming cycle and to improve system efficiency by providing an oval delivery port at a position shifted to a first lead-in part. CONSTITUTION:A first valve seat 16c having a suction port 16e to be coupled to the delivery side of a compressor in the inner face of a cylinder forming a valve body and a second valve seat 16d axially arranged with first and second lead-in ports 16f, 16g to be coupled respectively with outdoor and indoor heatexchangers are arranged in parallel. An oval delivery port 16a longer in axial direction of the cylinder and coupled to suction side of the compressor is provided at a position shifted to the first lead-in port 16f in the side face held between both valve seats 16c, 16d. When a holder 26 is moved axially through a solenoid, refrigerant paths can be switched.

    Abstract: PURPOSE:To smoothen a flow in low pressure side flow passage leading from a through hole to a lead-out port having an axially long elliptic form by widening the tip end of an inlet pipe leading to a compresor in a taper form and connecting it to the lead-out port. CONSTITUTION:A lead-out port 16a leading to an inlet pipe 17 which is connected to the inlet side of a compressor is opened on the side surface of a cylinder 16 for forming a valve main body. The lead-out port 16a has an axially long elliptic form, while the point 17a of the inlet pipe 17 connected to the cylinder 16 is widened in a taper form. Consequently, a flow is smoothened with a small pressure loss in a low pressure side flow passage on the outside of a slider 28 from the first through hole 20b or the second through hole 20c to the lead-out port 16a.

    Abstract: PURPOSE:To reduce the consumption of electric power, by connecting a transistor to an intermediate tap, in series with the primary coil and in parallel with the secondary coil, under using output of an electric discharge circuit and an integration circuit as input. CONSTITUTION:In the beginning of energizing of an electromagnetic coil 38, as voltage of an integration circuit 39b is low, a transistor 39c is in on-state, therefore only the primary coil 38e is energized for attracting a plunger, through streaming big current to draw out a big attraction. When voltage of the integration circuit 39b rises for turning off the transistor 39c, after attracting the plunger, the circuit is changed to an electric circuit formed of the primary coil 38e and the secondary coil 38f, and the streamed current is restricted so as to be proportionate to the holding torque. If the power source is cut off momentarily by such as momentary power failure, the plunger can be attracted certainly after the power source is restored, by function of an electric discharge circuit.

    Abstract: PURPOSE:To increase effective magnetic flux for obtaining a large attraction force by constituting in such a way that the flux obtained by passing a current through an electromagnetic coil is passed only through a magnetic circuit formed by a plunger, a fixed iron core, and a yoke so as to prevent it from leaking to other parts. CONSTITUTION:A sliding valve 40 which slides in the axial direction inside a cylinder 33 having four conduit pipes 34, 37-39 to change over a refrigerant circuit is provided. And a plunger 43 connected to the sliding valve 40 and a cover 46 fitted in the one end of the cylinder 33 are provided, and on the center hole part 46a of the cover 46 a plunger guide 44 which houses the plunger 43 in its inside and is fitted with a fixed iron core 45 at its end is provided. Further, an electromagnetic coil 48 which drives the plunger 43 and is fixed on the outside of the plunger guide 44, and a yoke 49 which forms a magnet path outside the electromagnetic coil 48 are provided. And the whole constituting parts except the plunger 43, the fixed iron core 45, and the yoke 49 are all formed with non-magnetic materials.
