Title: Pressure reducing valve containing steam dryness measuring function
Inventor: MORII TAKAYUKI
IPC: G05D16/16
Filed: 1990-03-15
Abstract: PURPOSE:To omit a throttle valve and a double pipe by providing the pressure detection members at the primary and secondary sides of a main valve port of a pressure reducing valve together with a temperature detection member provided at the secondary side and operating the dryness of the steam passing through the reducing valve from those detected pressure value and temperature value. CONSTITUTION:The waterdrop-like liquid component of the steam supplied through an inlet 12 is almost separated from the steam at a separator part 2 by the centrifugal force. Thus the steam has a comparatively high degree of dryness. When the dryness is measured for the steam from which the liquid component is substantially separated at the part 2, the primary steam pressure P1 is detected by a primary pressure sensor 6 attached to a primary pipeline 60 in a stable state of the detection value of a temperature sensor 8. At the same time, the pressure P2 of the throttled steam passed through a main valve port 14 is detected by a secondary pressure sensor 7 together with a temperature T2 detected by the sensor 8 respectively. These results of detection are inputted to an arithmetic part 5. In such a constitution, no separate throttle valve nor double pipe is needed.

Title: Swash plate compressor
Inventor: KAWASHIMA KENICHI
IPC: F04B25/04
Filed: 1978-06-07
Abstract: PURPOSE: To improve the lublicating performance at the time of the start by feeding oil collected in the interior of the compressor into a swash plate chamber by making use of a boiling phenomenon at the time of the start.  
     CONSTITUTION: When a compressor is stopped, coil collected in the form of a layer on the inner wall of the swash plate chamber 11 and oil and attached in the form of a film to the frictional surface of the swash plate enters an oil tank 25 if the volume of oil is greater than the volume of the swash plate chamber. When the compressor is started in this state, the frictional surface of the swash plate is lublicated by oil present in a bottom portion of the swash plate chamber 11. Then, the pressure in the oil tank is quickly reduced due to the withdrawing action of the compressor. As a result, the cooling medium that has been dissolved in the coil within the oil tank 25 is boiled off, and the oil is caused to flow through a small hole 26 and swash plate chamber 11 into low pressure chambers 9 and 10, In the above way, the frictional surface of the swash plate is lublicated by the oil and held in an ideal lublicated state.
