Patent number: 4431027Abstract: A remote fluid reservoir blow-molded of polymeric material is provided with an antechamber for the reception of incoming high velocity fluid and impinging of same in a sinuous course on walls of the antechamber which are so configured as to smoothly reduce flow velocity and avoid undue turbulence upon introduction of the fluid into a main storage chamber.Type: GrantFiled: April 21, 1981Date of Patent: February 14, 1984Assignee: General Motors CorporationInventor: John J.

Patent number: 4424829Abstract: A reservoir vessel intended for storage of a small volume of reserve fluid in an automobile for a remotely located power steering or like system connected with the reservoir by flexible hoses and including a baffle structure for redirecting the incoming high velocity flow from the system to mix within the reservoir without undue turbulence and air entrainment.This invention relates to vehicle fluid power systems and more particularly to an improved reservoir therefor.The modern trend in vehicle design, front wheel drive and otherwise, creates even further premium on space in engine compartments, and a corresponding emphasis in redesigning engine-related accessories. In power steering and like fluid power systems, it is now often desirable to separate the fluid reservoir from what formerly had been unitary association with a submerged engine-driven pump, and rather to situate it remote from the engine and connect it to the steering gear and pump by flexible hoses.Type: GrantFiled: April 12, 1982Date of Patent: January 10, 1984Assignee: General Motors CorporationInventors: Donald L. Millington, Gerald A. Nyquist
