Abstract
The present disclosure provides a heat exchanger system for a servovalve, comprising a base comprising a supply port in fluid communication with a return port, a first passage for fluid connection to a source of cooling fluid, and a second passage in fluid communication with the return port. The system further comprises one or more pipes located over a surface of the base, the one or more pipes fluidly connected between the first passage and the second passage, such that in use cooling fluid may flow from the first passage to the second passage via the network of pipes.
Claims12
A pneumatic servovalve comprising;
- a torque motor;
- and
- a heat exchanger system, the heat exchanger system comprising:
- a base comprising a pneumatic fluid supply port in fluid communication with a pneumatic fluid return port to allow a pneumatic fluid leaving the pneumatic fluid supply port to flow through the pneumatic fluid return port, a first passage for fluid connection to a source of a cooling fluid, and a second passage in fluid communication with the pneumatic fluid return port;
- and
- one or more pipes located adjacent a surface of the base, the one or more pipes fluidly connected between the first passage and the second passage, such that in use the cooling fluid is configured to flow from the first passage to the second passage via the one or more pipes to be combined with the pneumatic fluid flowing through the pneumatic fluid return port,
- wherein the torque motor is located over the surface of the base, and the one or more pipes are located between one or more components of the torque motor and the base.
