Publication number: 20100139625Abstract: A fuel vapor control valve comprising a housing. The housing comprising inlet and outlet ports in flow communication via first and second valve controlled passages. The first valve controlled passage being configured to admit fuel vapor flow in a direction from the inlet port to the outlet port only when pressure at the inlet port exceeds a predetermined threshold. The second valve controlled passage being configured to admit vapor flow in a direction from the outlet port to the inlet port only when pressure at the inlet port drops below pressure at the outlet port. The fuel vapor control valve further comprising a sealing arrangement disposed at an external portion of the housing between the inlet and outlet ports.Type: ApplicationFiled: December 1, 2009Publication date: June 10, 2010Applicant: RAVAL A.C.S. LTD.Inventors: Omer VULKAN, Vladimir OLSHANETSKY, Alon LEVY

Patent number: 6899119Abstract: A valve comprising a housing defining a control space with an outlet port for fluid egress from the space and at least one inlet port for fluid ingress into the space control member is displaceable between an open state in which the outlet port is open and a closed state in which the outlet port is closed. The at least one inlet port of the at least one inlet port is formed at a wall portion of the housing at an upper wall portion, and a fluid draining port is formed at or adjacent a bottom end of the housing for draining fluid from the control space. The fluid draining port serves for preventing fluid ingress into the control space.Type: GrantFiled: February 14, 2001Date of Patent: May 31, 2005Assignee: Raval-Agriculture Cooperative Societies Ltd.Inventors: Moshe Ehrman, Udi Orenstein, Zohar Moalem, Yoav Livne, Vladimir Olshanetsky
