Abstract: A refrigeration system for use in an automotive air conditioner comprises a compressor for compressing vapor-phase refrigerant, a condenser connected to the outlet of the compressor, an expansion valve connected to the outlet of the valve, and a vapor pressure-adjusting valve mounted in the passage extending from the evaporator to the compressor. When the vapor pressure inside this passage is less than a certain value, the adjusting valve reduces the flow of refrigerant from the evaporator to the compressor to maintain the vapor pressure constant. A part of the liquid-phase refrigerant on the downstream side of the condenser is added to the refrigerant evaporated by the evaporator, by means of the adjusting valve.

Abstract: A structural arrangement for an evaporator producing a uniform temperature gradient across its width. The structure is arranged so as to even out the flow of refrigerant within the evaporator. A first tank portion has a inlet and a second tank portion has a outlet. One end of each of plural tubes are connected thereto. A plurality of tubes allow refrigerant to flow from the first tank portion to the second. The tubes are arranged so as to provide equal flow distances for refrigerant across the evaporator, taking into account the directions of flow in the first and second tank portions. In a second embodiment, the inlet port and the outlet port are disposed at the first tank portion and the second tank portion respectively in such a manner that directions of the refrigerant flow within the first tank portion and the second tank portion are opposite to each other.

Abstract: A fluid pressure passageway (14) such as a high pressure fuel line in a fuel injection system is pressurized to an upper predetermined value. Then, the passageway (14) is isolated and the length of time for the pressure to drop to a lower predetermined value is measured. The greater the degree of leakage, the shorter the measured length of time. An alarm (24) is energized when the measured length of time is shorter than a predetermined length of time.

An alarm is produced when the voltage exceeds a predetermined value or range. A second voltmeter (23) is energized to display the voltage when the alarm is produced.

Abstract: A sensor (16) produces an electrical signal corresponding to the pulsating pressure in a high pressure fuel line (13) leading to a fuel injection valve (14), the pulsations being produced by opening and closing of the valve (14). The electrical signal and a reference signal are fed to a cathode ray tube display unit (18) to produce a Lissajous figure. The shape of the Lissajous figure indicates whether the Schnarren phenomenon is present and, if so, to what extent. The frequencies or amplitudes of the electrical signal and reference signal are compared to produce a signal indicating the difference therebetween which is fed to a digital display unit (22).
