专利汇可以提供Stirling cycle-type thermal device servo pump专利检索，专利查询，专利分析的服务。并且A servo pump assisting a pulsating primary pump. A Stirling cycle engine drives an expansible chamber pump in series with the primary pump. Pulses are transmitted from the primary pump to drive the displacer piston of the engine to drive the pump in phase with the primary pump.，下面是Stirling cycle-type thermal device servo pump专利的具体信息内容。
1. A servo pump for assisting a pulsating primary pump comprising: a Stirling cycle engine having displacer and power piston means; an expansible chamber pump driven by said power piston, means connecting said expansible chamber pump in series with said primary pump; and means for transmitting pulses from said primary pump to initiate drive of said displacer piston to thereby actuate said engine to drive said expansible chamber pump in phase with said primary pump.
2. A servo pump for assisting a pulsating primary pump comprising: a Stirling cycle engine having displacer and power piston means; an expansible chamber pump driven by said power piston, means connecting said expansible chamber pump in series with said primary pump; and means for transmitting pulses from said primary pump to initiate drive of said displacer piston to thereby actuate said engine to drive said expansible chamber pump in phase with said primary pump, wherein said means for transmitting pulses comprises a fluid column interconnecting said primary pump and said engine, and means for translating fluid pressure pulses transmitted through said column to mechanical movement to actuate said displacer piston.
3. A pump in accordance with claim 2 wherein said means for translating includes a diaphragm bisecting a chamber with one side thereof communicating with said fluid column and the other with ambient pressure.
4. A pump in accordance with claim 3 wherein said means for translating further includes a drive rod interconnecting said diaphragm and said displacer piston.
5. A pump in accordance with claim 3 wherein said means for transmitting pulses further comprises a return fluid column and valve means provide flow from said primary pump, through said one side of said chamber and back to said primary pump through said return column.
6. A pump in accordance with claim 1 wherein said expansible chamber pump comprises a pump housing, a pump piston reciprocable in said pump housing, means connecting said pump piston to said drive piston and inlet and outlet means communicative with said pump housing.
7. A pump in accordance with claim 6 wherein said pump piston divides said pump housing into inlet and outlet chambers, said inlet and outlet means comprising check valve controlled conduits communicating with said inlet and outlet chambers, respectively, and check valve means disposed through said pump piston to provide transfer of fluid from said inlet to said outlet chambers.
