Pump and valve combination for bladder adjustment

A pump and valve combination for bladder adjustment comprising:

• a fluid supply member having
• a head end,
• a tail end opposite to the head end,
• a driving member including a motor fixed on the head end thereof and a transmission part,
• a bottom cover disposed on the tail end thereof, and
• a diaphragm member arranged between the bottom cover and the driving member while the transmission part driven by the motor further driving the diaphragm member so that fluid is pumped and delivered into the bottom cover by the diaphragm member;
• a valve member arranged at the head end of the fluid supply member and including
• a valve cap fixed on and connected to the head end of the fluid supply member,
• at least one solenoid operated directional control valve mounted in the valve cap, and
• at least one air supply tube mounted in the valve cap and communicating with a bladder;
• and
• a bypass line located on one side of the motor and one side of the diaphragm member and including one end thereof communicating with the bottom cover while the other end thereof is extended to the valve member;
• wherein one end of the motor is close to the valve member while the diaphragm member is on the other end of the motor, opposite to the valve member;
• the fluid pumped and delivered into the bottom cover by the diaphragm member passes through the bypass line to be supplied to the valve member;
• wherein the other end of the bypass line is communicating with an air input end of the air supply tube and an air output end of the air supply tube is connected to an input portion of the solenoid operated directional control valve while an output portion of the solenoid operated directional control valve is connected to the bladder.
