Title: Shaft seat device for compressor in refrigerator
Inventor: CHO RIYOUSUKE
IPC: F16J15/34
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of refrigerant gas in the machine space, due to a drying state of sealing slide surfaces of a mechanical seal for a compressor in a refrigerator when the compressor comes to a stop. SOLUTION: A lip-like seal 4 having a cut-out 4a in a circumferential part of the outer peripheral part thereof is fitted on the machine space S1 side in a mechanical seal 3, the cut-out facing upward. During operation of the compressor in the refrigerator, mist-like refrigerator oil flows into and is pooled in a space S1 ' between the lip-like seal 4 and the mechanical seal 4, and thus pooled oil intervenes between sealing slide surfaces 30 of the mechanical seal 3 in the form of an oil film. Further, in this state is maintained even though the compressor comes to a stop, thereby it is possible to surely prevent leakage of the refrigerant gas.

Abstract: PURPOSE:To discover even the minute abnormality of the moving state of a moving body at an early stage, by forming not only the moving body to a conductive body but also two rails to a resistor and constituting a bridge circuit of two rails and the resistor. CONSTITUTION:When a moving body 1 moves on rails 2, 2' in parallel to said rails, voltages Va, Vb of detection terminals are equal and the voltage between detection terminals comes to zero. When the moving body 1 comes to the state shown by a broken line (a), a current ia flows through the moving body 1 from the rail 2' to the rail 2. When the current ia flows to a resistor 3, the voltage Va of the detection terminal becomes larger than the voltage Vb of the other detection terminal by voltage drop DELTAV and voltage of DELTAV bolt can be detected between the detection terminals. Next, when the moving body 1 comes to the state shown by a broken line (b), a current ib flows through the moving body 1 from the rail 2 to the rail 2'. Therefore, when the current ib flows to a resistor 4, the voltage Vb of the detection terminal rises by DELTAV' and becomes higher than the voltage Va of the detection terminal. By this constitution, the parallelism of the moving body can be detected certainly.
