A hydraulic bicycle component includes a first section and a first seal rupturing structure. The first section defines a first fluid path. The first seal rupturing structure is disposed in the vicinity of the first fluid path. The first seal rupturing structure is configured to physically rupture a first seal of a first hydraulic hose when the hydraulic bicycle component is coupled to the first hydraulic hose.

A gladhand assembly having a conduit for carrying a fluid and a port having a sidewall defining an interior region. The port also having a first opening in communication with an external environment and a second opening in communication with the conduit. The port includes a first recess in the interior region and disposed in the sidewall. There is a filter member including a sidewall and a first opening including a rim. The rim extends outwardly from the sidewall in a radial direction and is seated on the first recess in the sidewall of the port. There is a seal member configured to engage with and close the first opening in the port and the seal member includes a film having a first surface facing the external environment and a second surface facing the interior region of the port. The film includes a re-closable aperture.

A brake hose support structure of a vehicle includes a brake hose through which pressure fluid is flowed between a pressure source mounted to the vehicle and a brake caliper of a disk brake device of the vehicle, and a hose support supporting the brake hose. The brake hose has a first end that is located adjacent to the pressure source, a second end that is located adjacent to the brake caliper, and a supporting portion that is disposed between the first and second ends. The hose support supports the brake hose at the supporting portion such that an axis of the brake hose extends parallel to a kingpin axis.

A brake tube connector comprising a brake tube with a flare at an end, and a screw, the end having a front abutment surface, a rear abutment surface, and an intermediate portion between. The screw is arranged coaxially with the brake tube with threads and an abutment surface facing the rear abutment surface. The rear portion has an inclination angle between the rear abutment surface and a radial plane. The screw abutment surface screw is an angle between the screw abutment surface and a radial plane. A brake tube connector assembly includes the brake tube connector and a nut. The nut comprises a cylindrical recess having interior threads and an abutment surface. The nut receives the flare and the screw so that the interior threads engage with the screw's exterior threads, and the front abutment surface of the flare contact the abutment surface of the nut.

A connection assembly comprising a motor vehicle fluid line and a connection fitting, wherein the motor vehicle fluid line includes an inner tube made of aluminum. The connection fitting is in contact with the inner tube. At least the surface of the connection fitting is made of aluminum, at least in the region of the contact surface between the connection fitting and the inner tube.

A gladhand coupling that prevents inadvertent separation of the coupling halves without the need for additional structure or manipulation to connect and disconnect the halves. Each half is equipped with a lug having two spaced apart ramped pads and a flange defining a channel having a corresponding ramped pad. When two halves are positioned together then rotated into the locked position, the ramped pad of the flange is positioned proximately to the either of the ramped pads of the flange to prevent inadvertent lateral compression of the two halves that would otherwise cause unintentional uncoupling. The coupling may be disconnected by simple rotation of one coupling half relative to the other so that the ramped pad of the lug is positioned between the spaced apart ramped pads of the lug and by pulling the coupling apart as done by current rail car decoupling procedures.

A circuit for controlling current in an inductive load is provided. The circuit includes a driver circuit for driving a load current in the inductive load. The driver circuit includes a switch, which is switched on to increase the load current and a recirculation diode, which re-circulates the load current when the switch is off. The circuit includes a control module that generates a control signal to switch on and off the switch. The control module includes a PWM current controller comprising a negative feedback closed loop implementing at least a proportional control and an integral control. The PWM current controller receives a target current value and an estimated current flowing in the load during a measurement PWM cycle. The PWM current controller generates the control signal for a control input of the switch based on an error between the target current and the estimated current.

Check valves are disclosed and include a housing defining an internal cavity having a first seat and a second seat, and a seal member within the internal cavity translatable between a closed position against the first seat and an open position against the second seat. The second seat has a middle axis transverse to a plane of a longitudinal cross-section of the housing and has a shortest finger positioned to either the left or to the right of the middle axis. The seal member is seatable against the second seat at an angle or in a deflected position against the plurality of fingers, thereby defining a longer distance of travel to reach the closed position for a portion of the check valve disc that is associated with the position of the shortest finger relative to other portions of the check valve disc.
