Title: Hermetically closed coolant compressor
Inventor: KOUSOKABE HIROKATSU
IPC: F04C28/28
Filed: 1983-03-14
Abstract: PURPOSE:To make it possible to automatically protect the titled compressor from overheating and overloading by causing the compressor to display a shape memory effect at a temperature in the limit of the rise in the temperature of the compressor and lifting a delivery valve. CONSTITUTION:When discharge pressure is large and suction gas is in an overheated state, the temperature rises up and the temperature around the periphery of a discharge valve reaches at the value of 120 deg.C or more. As a result, a push- up plate 15 displays shape memory effect and assumes straight elongated shape to lift a delivery valve 11 as shown in (b) in the drawing. In this state, a compression space assumes a blow-through state and does not carry out compressing operation. Hence, the coolant gas having low temperature flows out as shown by arrow, and the overheated or overloaded driving is automatically prevented.
