摘要： PURPOSE:To obtain a vane side seal of contactless low torque not depending upon thermal expansion of a member, by placing a movable element between a vane and side plate. CONSTITUTION:A movable element 22 is inserted between a vane 20 and side plate 26. If the vane 20 travels in the direction of an arrow mark A, pressure in a vane chamber at the side of high pressure is acted upon back side part 27 of the movable element 22, to apply force fc to the movable element 22. While a power step bearing is formed between the movable element 22 and the side plate 26, and positive pressure is generated by shearing force due to a wedge oil film to apply force fB to the movable element. In this way, clearance delta1 between the movable element 22 and the side plate 26 can be always maintained to a constant value despite thermal expansion of the vane 20 and the like, thus a vane side seal not depending upon thermal expansion of members can be obtained.

摘要： PURPOSE:To make a high-precision control of a rotary compressor operation by providing a valve, which operates under a centrifugal force of a rotor, inside the rotor of a rotary compressor to form a by-pass, and making the valve to operate without being influenced by the pressure condition inside the by-pass and/or a vane room. CONSTITUTION:Normally, a by-pass 15 and 16 are being closed by an outer peripheral surface of a spool 9 for a coolant never to make a leak from a high-pressure side vane room 3 into a low-pressure side vane room 6. When a revolving speed rises and a centrifugal force becomes greater than that of a spring 11, the spool 11 rises to open the by-passes 15 and 16. Since a communicating hole 10 is provided through the center of the shaft of the spool 9, a gas can freely flow through a cylinder 13. Accordingly, there is no restriction to the movement of the spool 9 in its axial direction due to the gas pressure for the spool 9 to be moved only by the centrifugal force of the rotor. Therefore, the opening/closing operations of the control valve for controlling the compressor performance will hardly be influenced by the gas pressure any longer, to be capable of performing a high-precision control of the compressor operation.

摘要： PURPOSE:To minimize the leak of refrigerant as well as prevent the baking seizure of vane-sliding face by forming a dynamic pressure bearing by which to positively generate a pressure by wedge oil film in the relative moving surface between the side of vane and a side plate. CONSTITUTION:The side 10 of a vane 4 is formed at an obtuse angle, not right angle, to the sliding face 7 on running side. If the sides of both faces of a vane 4 are shaped into tapered form, oil film between both faces relatively slides in the form of a wedge and a shearing pressure is therefore generated by the wedge oil surface. And, when high-viscous lubricating oil exists abundantly on the side of the rotor 2, an oil surface is effectively formed, so that the leak of refrigerant traversing the vane 4 can be minimized by setting up proper taper angle of the vane 4, and also baking seizure encountered during the high-speed rotation can be prevented.

摘要： PURPOSE:To protect a gas burner from overheating and burning and keep it safe by a method wherein a gas pressure regulator and a gas valve connecting with a temperature detector are brought into parallel and the flow rate of the gas jetted from a nozzle is controlled. CONSTITUTION:Gas is supplied to a main nozzle 40 through a supply pipe 1, a gas pipe 5 and a gas pressure regulator 6 which is capable of controlling gas volume and at the same time is supplied in parallel with them to the main nozzle 40 through a gas valve body 7. Here, when a heated matter 38 rises in temperature by combustion of a main burner 8, a contact 32 of a temperature detector 41 is heated and reaches the Curie point of ferrite 30 of about 100 deg.C, the contact loses attractive force to a magnet 31, the rod 37 falls and a gas valve 23 is closed by a spring 24. When the heated matter 38 takes the desired temperature thus, the combustion gas quantity is squeezed automatically in order to prevent excessive rise of temperature. The combustion gas quantity can be set previously by a knob 18.
