<P>PROBLEM TO BE SOLVED: To provide a bubble removing device which requires a small occupied space and which can efficiently remove bubbles existing in operating oil and bubble nuclei melted in the operating oil. <P>SOLUTION: A bubble removing device 100 for a work machine includes a high-pressure chamber 1 into which high-pressure operating oil is introduced through a high-pressure introduction port 11, a low-pressure chamber 2 into which low-pressure operating oil is introduced through low-pressure introduction ports 21a, 22a, 23a, 24a, a partition wall 3 parting the high-pressure chamber 1 from the low-pressure chamber 2, and an exhaust pipe 5 fixed to a cover plate 1b of the high-pressure chamber 1 and the partition wall 3, and having a lower end protruded into the low-pressure chamber 2. A swirl flow R is generated in the low-pressure chamber 2 and a jet flow J is generated by a throttle 4 provided in the partition wall 3 and jetted into the low-pressure chamber 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
