摘要： Equipment for working a hard material includes a housing (2), a driving motor (1), located within the housing, a cooling duct (3) within the housing surrounding the driving motor, a tool (5) for working the hard material connected to the driving motor and at least one electronic component (19) mounted on a cooling device (8). A coolant supply source (6) supplies coolant under pressure to the cooling device (8) and then to an upstream end of the cooling duct (3). A first coolant discharge pipeline (13) is connected to a downstream end of the cooling duct (3). The first coolant discharge pipeline (13) flows the coolant into a reversible distributor (10). A second and a third coolant discharge pipeline (11, 12) extend from the reversible distributor (10) so that selectively all of the coolant can flow through the second coolant discharge pipeline (11) to the tools (5) or all of the coolant can flow through the third coolant discharge pipeline (12) to the coolant supply source or a part of the coolant can flow through each of the second and third coolant discharge pipelines. To operate the equipment if coolant flows through the cooling device (8), a flow monitor (14) detects the movement of coolant and sends an electronic signal to the electronic component (19). The power is supplied from an external power source to the driving motor (1) only when the flow monitor (14) signals that coolant is flowing.
