  • Patent number: 11905979
    Abstract: A piston, in particular for a gear-change selector, including a piston body with a piston skirt and with a piston end face which can be pressurised with a working fluid. The piston includes a first sealing portion and a second sealing portion. The piston body and the first sealing portion have mutually complementary geometries so that they form a first vent channel. The first vent channel is arranged in a hydraulic series circuit with the second sealing portion. The second sealing portion prevents venting up to a first pressure and allows this above the first pressure. The invention furthermore concerns a gear-change selector and a gearshift for a vehicle.

  • Patent number: 10413925
    Abstract: The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.

  • Patent number: 10335818
    Abstract: A dual dispenser having two pumps and an outlet channel that is fed with the fluids coming from both pumps. The two pumps include respective actuator rods that are movable axially over strokes of different lengths, namely a first actuator rod having a long stroke, and a second actuator rod having a short stroke. The common dispenser head includes a pivot member that forms two bearing elements that are constrained to move together, so as to move both actuator rods simultaneously over an axial height that corresponds to the short stroke, with one bearing element then continuing its movement so as to terminate its long stroke by pivoting and turning the pivot member about the bearing element that is blocked in position as a result of the second actuator rod already being fully depressed.
