Abstract: A fuel tank made of a plastic material and fitted with at least one fuel accessory attached to an inside surface of a wall thereof, wherein the fuel accessory is attached to a predetermined site at the inside surface by fusion welding. Further there is disclosed a fuel accessory for attaching to a site at an inside wall portion of a plastic material fuel tank, comprising a housing formed with an engaging surface attachable to the site. The engaging surface is fitted with a fusion melting element for fusion welding the fuel accessory to the fuel tank.

Abstract: A rotary valve having a fluid inlet and a fluid outlet, the rotary valve including a housing for mounting in a fluid line controlling an hydraulic or pneumatic system, and a ball assembly mounted in the housing, the ball assembly including: at least two intersecting fluid flow passageways; and a check valve mounted in an inlet of one of the passageways; the ball assembly and the housing being configured and adapted to permit fluid flow through the housing from the inlet to the outlet in all positions of the ball assembly, and to permit fluid flow through the housing from the outlet to the inlet in all except one position of the ball assembly, in which one position the check valve maintains pressure in the fluid line for locking the hydraulic or pneumatic system.

Abstract: A fuel vapor control valve comprising a housing fitted with an inlet port connectable to a fuel tank and an outlet port connectable to a fuel vapor recovery device. The inlet port and the outlet port are in flow communication via a first valve controlled passage admitting fuel vapor flow in a direction from the inlet port to the outlet port only when pressure within the fuel tank exceeds a threshold. A second valve controlled passage admits vapor flow in an opposite direction from the outlet port to the inlet port only when pressure within the fuel tank drops below pressure at the fuel vapor recovery device.

Abstract: The invention concerns a fuel tank (1) for a motor vehicle comprising a filler connection (2) enclosing a tank refueling passage (11) and operational and tank refueling venting conduits (3, 4) which are connected to a filler head (6) of the filler connection (2), wherein the filler head (6) has at least one change-over switching valve (9) which in a first switching position (tank refueling position) opens a flow path from the tank refueling venting conduit (3) to a fuel vapor filter and closes a connection of the operational venting conduit (4) to the tank refueling passage (11), and which in a second switching position (operational position) opens the connection of the operational venting conduit (4) to the tank refueling passage (11) and closes the flow path from the tank refueling venting conduit (3) to the fuel vapor filter.

Abstract: A roll-over vent valve comprising a housing formed with a fluid inlet and a fluid outlet, a valve seating bounding an outlet aperture of the housing, a float member received within the housing and axially displaceable between a sealed position wherein a sealing member thereof sealingly bears against the valve seating of the outlet aperture to seal the fluid outlet, and an open position wherein the sealing member is disengaged from the valve seating whereby the fluid outlet is in flow communication with the fluid inlet. There is further provided a pressure-retention device extending intermediate the valve seating and the fluid outlet, to thereby shut fluid flow therebetween as long as pressure differential between the fluid inlet and the fluid outlet does not exceed a minimal pressure threshold.

Abstract: A valve comprising a housing accommodating a first and a second outlet port, a first stage float member associated with the first outlet port and a second stage float member associated with the second outlet port. The float members are displaceable within the housing about parallel axes, between an open position and a closed position. The first stage float member at least partially overlaps over the second stage float member.
