  • Patent number: 7299631
    Abstract: An arrangement (10) for the connection of a brake fluid supply reservoir (12) to a longitudinal brake master cylinder (14) of a motor vehicle, in which at least one lower supply pipe (16) connected to the reservoir is received in a complementary supply bore (18) of the master cylinder (14) and in which vertical immobilization structure (20) is interposed between the pipe (16) and the master cylinder (14). The arrangement is by an intermediate baseplate (22) that is connected to the reservoir (12) by at least one nozzle (24) including the supply pipe (16) and that is lowered vertically onto the master cylinder (14) and then immobilized on the master cylinder (14) by way of vertical immobilization structure (20) that directly snap-fastens to the master cylinder (14) to allow rapid attachment of the pipe (16) to the master cylinder (14).

  • Patent number: 7299820
    Abstract: In order to prevent hydraulic fluid infiltrating out from a hydraulic fluid tank (1) when a vehicle is in operation, the invention provides for the tank to be compartmentalized by an anti-overflow partition (16). The anti-overflow partition is made in such a manner as to hold air captive inside the tank in the vicinity of a feed orifice (11) at a location placed in a top portion of said anti-overflow partition.

  • Patent number: 7270220
    Abstract: An adjuster arrangement for maintaining first and second brake shoes of a brake between a minimum and a maximum clearance with respect to a drum. The adjuster arrangement has a pawl located on a pivot pin on the first brake shoe and an arm that engages a star wheel of an expandable strut. A first leg of a thermo clip is held against the first brake shoe by the pivot pin and receives thermal energy generated during a brake application. During a brake application, the pawl pivots on the pin and imparts a rotary torque to the star wheel to expand the strut to create a maximum clearance while at the same time a predetermined temperature generated during a brake application acts on the thermo clip to moves the pawl out of engagement with the star wheel to prevent rotating the star wheel and thereby sustain a minimum clearance.

  • Patent number: 7261190
    Abstract: A lever for moving first and second brake shoes into engagement with a drum to effect a brake application. The lever has a first end connected to the brake shoes and a second end with a tine fixed thereto to which a cable is connected to apply an input force to effect a brake application. A predetermined force is applied to the tine to deflect the tine and a tab engages the lever to hold the tine in the deflected position. The tine and second end of the lever move in unison in response to an input force until the input force exceeds the predetermined force such that while the tine and cable continue to move in unison the deflection of the tine proportionally reduces the movement of the first end of the lever and as a result an actuation force applied to effect a brake application is correspondingly reduced.

  • Patent number: 7249660
    Abstract: A drum brake has cylinders symmetrically fixed to a stationary member. Each cylinder has an axial bore therein with a groove for retention of a seal. A piston engages each seal to define chambers that receive pressurized fluid. Webs for friction members have a first end pined to an opposite cylinder and a second end connected to an opposite piston and to each other by a strut. Pressurized fluid acts on the pistons to move the second ends with respect to the first ends and simultaneously bring the friction members into engagement with a drum to effect a brake application. The seals acts on and return the pistons to a rest position in an absence of pressurized fluid. A pawl on a lever is moved into engagement with the strut to bring the first and second friction members into engagement with the drum to manually effect a brake application.

  • Patent number: 7240602
    Abstract: A device comprised a master cylinder driven by a control member (20), a pneumatic booster (14), a piston (22), first (VE1) and second (VE2) balancing valve elements, first (VA1) and second (VA2) intake valve elements, and a tubular support (44) provided with two parts (44A, 44B) move relative to one another to adjust the length of the support (44). The balancing valve elements (VE1, VE2) are borne by a balancing part (44B) of the support and the pneumatic piston (22). The intake valve elements (VA1, VA2) are borne by the control member (20) and an intake part (44A) of the support. The two parts (44B, 44A) of the support are connected to one another by a spring (54) and arm (56) arrangement for adjusting the separation thereof as a function of the power of the force applied to the control member (20).

  • Patent number: 7213499
    Abstract: A spacer secured to a dash panel offsets a boost unit of a brake system into an engine compartment. The spacer has a cylindrical body with a u-shaped space through which air from the engine compartment is communicated to the boost unit to effect a brake application. The u-shaped space is divided by a plurality of walls into first and second labyrinth paths around the cylindrical body. An open cell gasket is located between the boost unit and the spacer to seal the u-shaped space. Air enters the u-shaped space and is divided into equal volumes that flow around the cylindrical body to a radial opening in the cylindrical body for distribution to the boost unit. Air flowing along the first and second labyrinth paths encounters the open cell gasket and sounds generated in the engine compartment are attenuated by being absorbed prior to delivery to the boost unit.

  • Patent number: 7210747
    Abstract: A spinner apparatus for the adornment of a wheel on a roller skate. The spinner apparatus includes a cone, a first disc and a second disc. The cone is connected to the wheel and connected to the first disc by locating a lip on its periphery in groove on the periphery of the first disc. Radial openings that extend from an axial opening in the first disc to define a first plurality of spokes while radial openings extend from an axial projection in the second disc define a corresponding second plurality of spokes therein. The axial opening receives the axial projection to position the second disc adjacent the first disc. The first disc rotates with the wheel while the second disc independently rotates such that the first and second spokes interrupt the transmission of light to provide an illusion that the wheel is rotating faster than is actually occurring.
