Abstract
Oil circuit for lubrication and cooling of an oil-free compressor (1) comprising a motor (4) with a variable speed and a compressor element (2) driven by said motor (4), - whereby this oil circuit (5) is provided with an oil reservoir (10) with oil (11) and a rotary oil pump (13) configured to drive oil (11) from the oil reservoir (10) through an inlet channel (23) upstream the rotary oil pump (13) to the compressor element (2) and/or the motor (4) via an oil pipe (12); - whereby this rotary oil pump (13) is provided with a rotor (26) mounted on a rotation shaft (27), whereby this rotary oil pump (13) has a swept volume, and whereby this rotary oil pump (13) is driven by the motor (4) of the compressor element (2); - whereby the oil circuit (5) is further provided with a return pipe (19) configured to guide oil (11) from the compressor element (2) and/or the motor (4) back to the oil reservoir (10); - whereby the oil circuit (5) is further provided with a bypass pipe (15) and a pressure-actuated bypass valve (14) which are configured to directly guide a portion of the oil (11) between the rotary oil pump (13) and the compressor element (2) and/or the motor (4) back to the oil reservoir (10) without this portion of the oil (11) passing through the compressor element (2) and/or the motor (4) during its way back to the oil reservoir (10); and - whereby the oil circuit (5) is further provided with an oil cooler (16), characterised in that the oil cooler (16) is placed in the bypass pipe (15) and that the bypass valve (14) is placed in the oil pipe (12).
