摘要： A unitary valve assembly for a fluid-activated, percussive paving breaker includes a valve chest having an outer sidewall forming an internal valve chamber, a sidewall within the internal chamber forming a valve bore, a reciprocal valve within the valve bore and a bottom plate permanently fastened to the outer sidewall. The inner sidewall forms a first annular, upstanding sealing seat for the valve, and the bottom plate forms a second annular, upstanding sealing seat for the valve. Passageways through the valve assembly are positioned so as to connect with high and low pressure chambers of a paving breaker, when the valve assembly is inserted into the paving breaker. For weight reduction, the valve assembly is made of acetal resin.

摘要： A beverage syrup pump system is disclosed including a pump housing having an internal pumping chamber, a pump motor, and a pumping mechanism driven by the motor within the pumping chamber. The pumping mechanism receives a syrup fluid at a first pressure and discharges the fluid at a second pressure which is greater than the first pressure. A pressure transducer adjacent a sensor port and in contact with a quantity of the fluid at the second pressure generates an electrical signal based upon the second pressure. A programmable micro controller receives the electrical signal from the pressure transducer and is capable of starting and stopping the pump motor. The micro controller will immediately stop the pump motor if the second pressure exceeds a predetermined maximum pressure level. The micro controller will also stop the pump motor if the second pressure falls and remains below a predetermined minimum pressure level for a predetermined first time interval.
