Abstract

945,265. Fluid regulation. WORTHINGTON CORPORATION. Oct. 13, 1961, No. 36777/61. Heading G3H. [Also in Division F2] A variable throttle device for use in controlling the pressure of leakage fluid from a mechanical seal (see Division F2) comprises an element 84 mounted in a chamber 81 of a body 80 and axially movable by a threaded rod 85. The chamber 81 has a fluid inlet 82 and an outlet 83 and the element 84 is provided with seals 92 and 93 and transverse ports 89 and 90. In operation, fluid passes from the port 90 through the clearance between the element 84 and body 80 to the outlet 83 via a chamber 91, the degree of throttling depending on the length of path determined by the axial position of the element 84.
