In a connection of a hose clamp and a hose that is provided with projections, wherein the hose clamp surrounding the hose is pre-positioned between the projections before tightening of the hose clamp on the hose, the projections are arranged on opposed sides of the hose clamp and have gaps. A locking strip with laterally projecting tabs is fastened on an inner side of the hose clamp. The laterally projecting tabs engage in a positive-looking way the gaps.

A spring band clamp is comprised of an annular spring band having a first end portion and a second end portion. Each end portion has a spreading jaw that projects beyond a periphery of the spring band. The first end portion has a tongue spaced from the spreading jaw of the first end portion extending radially outwardly from a U-shaped incision in the first end portion and has a free end surface extending perpendicularly with respect to a direction of extension of the tongue. An abutment is formed by a radially inner edge of the free end surface of the tongue. The second end portion has a slot extending in a circumferential direction. The first end portion projects through the peripheral slot in the second end portion. The spring band exerts a closing spring force, which is directed in the circumferential direction. The closing spring force is greater in an open position of the spring band clamp than in an operative position. In the open position of the spring band clamp, a support surface of a free end of the spreading jaw of the second end portion bears, due to the closing spring force, against the abutment of the tongue. The support surface is disposed at an angle with respect to a radius of the clamp that intersects with a radially inner edge of the support surface. The spring band clamp is disengageable from the open position by relative radial movement of the end portions.

A spring band clamp is comprised of an annular spring band having a first end portion and a second end portion. Each end portion has a clamping jaw that projects beyond a periphery of the spring band. The first end portion has a tongue extending radially outwardly from a U-shaped incision in the first end portion. An abutment is formed by a radial inner edge of a free end surface of the tongue. The second end portion has a slot extending in a circumferential direction. The first end portion projects through the peripheral slot in the second end portion. The clamping jaws extend substantially tangentially relative to the circumferential direction of the spring band. The spring band exerts a closing spring force, which is directed in the circumferential direction. The closing spring force is greater in an open position of the spring band clamp than in an operative position. In the open position of the spring band clamp, a support surface of a free end of the clamping jaw of the second end portion bears, due to the closing spring force, against the abutment of the tongue. The support surface is disposed at an angle with respect to a radius of the clamp that intersects with a radial inner edge of the support surface. The spring band clamp is disengageable from the open position by relative radial movement of the end portions.

A clamp for hoses, pipes and the like which is intended to prevent leakage due to expansion of the clamp by increased internal pressures. The clamp has a clamping band with two ends. When the clamp is installed and in a generally unstressed condition, a projection on one end is spaced from an abutment on the other end. As internal pressure increases, the clamp expands until the projection engages the abutment. Further expansion is prevented.

A fuel dispenser seal to be used in an inlet of a fuel tank having an orifice of a reduced diameter. The seal comprises a sealing ring made of a polymer material which is provided with a sealing lip which can engage with the fuel dispenser. The sealing ring is held in a support body of a basically tube-like shape and in at least a partial section the support body is elastically configured and can be inserted into the inlet through orifice by a reversible diameter reduction. In the inlet it can engage with a projection of the inlet facing in radial direction towards the interior and it can be firmly attached in axial direction.

A device for the temporary storing and metered supplying of volatile fuel components present in the free space 22 of a fuel tank system 15 into the intake pipe 1 of a combustion engine 2. The device includes a deaeration pipe 25 which connects the free space 22 with the atmosphere 23 and in which a storage chamber 18 including an absorptive element is disposed. A pipe 20 connects the storage chamber 18 with the intake pipe and can be closed by means of an electromagnetic stop valve 13. An auxiliary valve 21 including a control chamber 14 which can be closed by means of a vacuum controller is disposed between the stop valve 13 and the intake pipe 1. A bypass 4 having an adjustable cross section is provided parallel to the auxiliary valve 21.

A louver for selectively closing flow openings defined therethrough comprising a stationary support grid including a plurality of equidistantly spaced, first rods extending in a first direction to define flow openings therebetween, a movable grid including a plurality of spaced, second rods extending parallel to the first rods and being movable relative to the first rods in a second direction perpendicular to the first direction from a first position in which each of the second rods at least partially overlaps a respective one of the first rods to a second position spaced from said first position by a distance approximately equal to the equidistant spacing between said first rods and a plurality of substantially impermeable, flexible, flat structures each having first and second longitudinal edges and each of which is connected along the entire length of its first edge to one of the first rods and along the entire length of its second edge to a respective second rod that at least partially overlaps said one first rod in the first position. The flat structures have a width that is at least as wide as the width of the equidistant spacing whereby when the second rods are moved to the second position the flat structures close the flow openings.

Louver

An apparatus for the temporary storage and controlled feeding of the volatile fuel components situated in the free space of a tank to the intake tube of an internal combustion engine. The apparatus includes a vent line connecting the free space to the atmosphere. In the vent line there is disposed a storage chamber containing an absorption element, as well as a line connecting the storage chamber to the intake tube, which can be shut off by an electromagnetic check valve. Between the check valve and the intake tube there is disposed an auxiliary valve with a control chamber. The auxiliary valve can be closed by a vacuum actuator in dependence upon the pressure difference between the control chamber and the atmosphere.
