'For purposes of illustration the invention is shown as incorporated in a pressure responsive control device which may be controlling the compressor motor of a compression refrigeration system in response to suction pressure. A casing II has a cup 11 hermetically sealed to its lower edge. A ...
A solenoid valve 4 is connected with a power source, being connected in series with a pressure switch 3 and contact 21, and a solenoid valve 6 is also connected with the power source, being connected in series with a pressure switch 5 and contact 71. As the compressor is started, the ...
the inverter circuit (10), a compressor (11) having a protection device (a pressure switch) (9), and a phase-voltage detection circuit (a U-phase voltage detection circuit) (6) that detects a voltage at any of three-phase windings (compressor windings) (8U-8W) of the compressor (11)...
The work of the compressor is controlled by the control switch. The utility model can realize the pressure increasing and reduction of the box body, and can cause the human body in the body-building apparatus with a pressure adjusting device to carry out static body-building. The utility ...
