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.
