| A fluid machine (101) includes a first compressor (107) and a second compressor (108). The first compressor (107) has a first closed casing (111), a first compression mechanism (102a), an expansion mechanism (104), and a shaft (113). A first oil reservoir (112) is formed in the first closed casing (111). The second compressor (108) has a second closed casing (125) and a second compression mechanism (102b). A second oil reservoir (126) is formed at a bottom portion in the second closed casing (125). The first closed casing (111) and the second closed casing (125) are connected to each other by an oil passage (109) so that a lubricating oil can flow between the first oil reservoir (112) and the second oil reservoir (126). An opening (109a) of the oil passage (109) on a side of the first closed casing (111) is located above the expansion mechanism (104) with respect to the vertical direction. This configuration prevents the high temperature lubricating oil in a surrounding space of the expansion mechanism (104) and the high temperature lubricating oil in the second compressor (108) from flowing. Thereby, the heat transfer between the first compressor (107) and the second compressor (108) is suppressed. | ||||||

| A process for monitoring the coolant level in a cooling system, in particular in a motor vehicle in which the relative pressure and the temperature of the coolant are measured on the high-pressure side of the coolant circuit, using the measured pressure value. A temperature assigned to the pressure value is established on the basis of a coolant specific function (temperature=f (pressure)) and the undercooling of the coolant is then determined by subtracting the measured temperature from the assigned temperature, which undercooling is analyzed as a measure for the coolant level. | ||||||
