Title:
WASTE HEAT USING DEVICE
Document Type and Number:
Japanese Patent JP2013142296
Kind Code:
A
Abstract:

To provide a waste heat using device having high performance and superior mounting characteristics.

A waste heat using device includes a Rankine cycle 3 used for a driving system 1. This Rankine cycle 3 has an electric pump P1, a boiler 15, an expander 17, an oil separator 19, a condenser 21, pipes 23-27, and an oil pump device 29. The oil pump device 29 has a device body 31, a high pressure passage 33, a low pressure passage 35, an inflow passage 37 and an outflow passage 39. The device body 31 has a housing. The housing is partitioned into a pressure sensitive chamber and an oil chamber by a diaphragm. In this waste heat using device, a working fluid flowed out of the boiler 15 flows in or flows out of the pressure sensitive chamber, so that lubricating oil flows in the oil chamber, and the lubricating oil of the oil chamber flows out. Thus, the oil pump device 29 recirculates the lubricating oil in the oil separator 19 to the expander 17.
