摘要： PROBLEM TO BE SOLVED: To improve a valve performance by increasing a valve opening area without increasing a size and without reducing a pressure resistance. SOLUTION: A control valve for variable displacement compressor 1 is provided with a body 2 installed in a valve storing chamber of a variable displacement compressor, a sealing member 25 which partitions the valve storing chamber into a suction pressure introduction chamber 22 and a control pressure introduction chamber 23, a communicating path 6 which communicates the suction pressure introduction chamber 22 with the control pressure introduction chamber 23, a bellows 16 which is displaced according to a pressure in the suction pressure introduction chamber 22, a valve element 18 which is displaced following to the displacement of the bellows 16 and opens and closes valve seats 14 and 15 in the communicating path 6, and a spring 26 which energizes a valve element 18 in the direction to open the valve seats 14 and 15. Also the valve element 18 is provided with a main valve part 19 which opens and closed the main valve seat 14 and an auxiliary valve part 21 which opens and closes the auxiliary valve seat 15, and both main and auxiliary valve parts 19 and 21 open and close both valve seats 14 and 15 simultaneously.

摘要： PROBLEM TO BE SOLVED: To improve valve performance by miniaturizing a valve apparatus, while minimizing the hysteresis in relationship between the suction pressure in a suction pressure introducing part and the pressure in a control pressure introducing part and ensuring the sealing between the suction pressure introducing part on the outer periphery of a body, the control pressure introducing part and a discharge pressure introducing part. SOLUTION: When the pressure in a suction pressure introducing part A introduced the inner chamber of a case 2 through a pressure introducing hole 21 is increased, a bellows 8 is contracted to displace a reciprocating shaft 83 to the left side and a spherical valve body 6 for contracting or closing the opening for a valve seat 11a by an energizing force of a leaf spring 7. When the pressure in the suction pressure introducing part A is reduced, the bellows 8 is extended by the internal pressure and the energizing force of a coiled spring 84 to press the spherical valve body 6 through the reciprocating shaft 83, so that the spherical valve body 6 is displaced to expand the opening for the valve seat 11a and introduce a portion of the discharge pressure in the suction pressure introducing part A to the control pressure introducing part B through a communicating path 11. The spherical valve body 6 is always supported by a leaf spring 7 concentrically with the valve seat 11a.

摘要： PURPOSE:To display speed and distance accurately by constituting a speedometer of an electromagnetic pickup for emitting its output according to passing spokes, a circuit unit for converting the output from the electromagnetic pickup into speed signals and a display unit. CONSTITUTION:An electromagnetic pickup 11 is arranged in a fork unit 13 of a bicycle wheel while facing spokes 12. A meter unit 15 is constituted of a circuit unit 14 and a display unit 27, and is arranged on the handle unit 16 of a bicycle. The electromagnetic pickup 11 and the meter unit 15 are connected to each other by means of a lead wire. When the spokes 12 pass through the front part of the electromagnetic pickup 11 according to rotation of the wheel, magnetic flux density of magnetic field varies so that electromotive force can be generated in the electromagnetic pickup 11. In the circuit unit 14, generated output voltage is converted into a speed signal and a travel distance signal by means of A-D converter unit and so on so as to be outputted to the display unit 27.
