A vehicle suspension spring system for a vehicle wheel station includes a hydraulic cylinder or strut having a piston which divides the cylinder volume into a main oil volume and an annular oil volume. The main oil volume communicates via a first oil passage with a first accumulator having a main gas volume. The annular oil volume communicates via a second oil passage with a second accumulator having an auxiliary gas volume. The oil in each accumulator is separated from the gas by a separator piston or diaphragm. A third oil passage with an isolating valve interconnects said first and second oil passages. Operation of the isolating valve is regulated by a controller. At least one sensor for sensing a parameter associated with vehicle attitude is connected to the controller. The controller is operable for switching the isolating valve between open and closed positions for altering spring stiffness of the strut in response to said sensed vehicle attitude parameter when the vehicle is in motion.

This invention relates to a drain plunger that snakes clogged drains at the same time that the drains are being plunged. The “snake plunger” includes a pleated bellows forming a head section which is removably coupled to a handle. Further, in one embodiment, the head and handle sections are jointly configured to release air from within the bellows while the plunger is being inserted into a basin filled with wastewater, thereby reducing or eliminating potential spillover. Further, a flexible elongated snake disposed within the interior of the bellows enters the drain as the plunger bellows is compressed. The snake is capable of dislodging and breaking up obstructions within a drain. Further, the snake may also have a hook at its lower end that is capable of snaring items causing obstructions within the drain. These features combine to create a plunger that provides a superior ability to effectively clear clogged drains.
