Manifold assembly

A surface assembly comprising:

• a covering defining an interior;
• first bladders disposed within the interior;
• second bladders disposed within the interior, and wherein each of the first and second bladders are operable between an expanded condition, a neutral condition, and a compressed condition;
• a pump having an inlet port and an outlet port, wherein the pump is configured to provide positive pressure through the outlet port and negative pressure through the inlet port;
• and
• a manifold assembly in fluid communication with the pump and each of the first and second bladders, the manifold assembly including:
• a manifold core having an inlet tube in fluid communication with the outlet port and an outlet tube in fluid communication with the inlet port, and wherein the manifold core has a first projection in fluid communication with the first bladders and a second projection in fluid communication with the second bladders;
• a connector operably coupled to the manifold core, wherein the connector defines first and second pathway regions and release notches;
• and
• a motor operably coupled to the connector, wherein the motor is configured to rotate the connector relative to the manifold core to fluidly couple the first bladders to the inlet port and the second bladders to the outlet port in a first operating state to expand the first bladders and vacuum the second bladders and the first bladders to the outlet port and the second bladders to the inlet port in a second operating state to vacuum the first bladders and expand the second bladders, and wherein the motor is configured to rotate the connector relative to the manifold core to fluidly couple the first and second bladders with the release notches in a release state where the first and second bladders are free of communication with the pump to adjust to the neutral condition.

A pneumatic system, comprising:

• first bladders;
• second bladders arranged in an alternating pattern with the first bladders;
• a pump configured to provide positive pressure and negative pressure;
• a manifold assembly fluidly coupled to the first and second bladders and the pump, wherein the manifold assembly includes:
• a manifold core having an engagement surface defining apertures in fluid communication with an inlet tube, an outlet tube, a first projection, and a second projection, respectively;
• a connector defining a first pathway region, a second pathway region, and release notches;
• and
• a motor configured to rotate the connector relative to the manifold core;
• and
• a controller communicatively coupled with the pump and the motor, wherein the controller is configured to:
• activate the motor to rotate the connector to fluidly couple the inlet tube with the first projection and the outlet tube with the second projection in pressurized operating states;
• and
• activate the motor to rotate to the connector to align the release notches with the apertures in fluid communication with the first and second projections in release states, wherein rotational positions of the connector alternate between the pressurized operating states and the release states to adjust the first and second bladders between a first pressurized condition and a second pressurized condition via a neutral condition.
