Abstract
1,265,234. Valves. C. BUBKERT. 3 April, 1970 [5 April, 1969; 17 Nov., 1969], No. 15842/70. Heading F2V. The spool 8 of a multi-way valve reciprocates in a hardened control bush 4 which is disposed in an outer bush 2 having sealing elements 3 and secured fluid tight to the casing 1. The outer bush is injected or cast into the metal or plastics housing and is formed with end shoulders 11, 12 which centre the bush 4 when it is inserted. Other shoulders 14, 15 &c. are clear of the outer surface of the bush 4 to allow flexing and hold sealing elements in the form of O-rings or lip rings. The bush 4 is held in place by the inturned ends of two sleeves 6, 7, the ends of which may be made flexible by slitting to allow axial movement of the bush 4. The outer bush may be assembled from separate rings which are cemented in the housing and may be sealed on its outer circumference with 0-rings. The sealing elements may be replaced by lip seals moulded with internal inclined lips and outer peripheral edge projections between which is an axial surface having a moulding burr therearound, the burr being radially inward of the projections.
