A rotary engine and a hydraulic motor including non-rotary outer and inner casings; a power shaft with an eccentric part; a driving eccentric ring between the outer and inner casings and mounted on the eccentric part; a combustion or pressure chamber between the eccentric ring and the inner casing such that the eccentric ring drives the power shaft by substantially non-rotating eccentric movement; dividers for dividing the combustion chamber into at least two parts, the dividers extend through the inner casing and are in contact with an inner surface of the driving eccentric ring; and an eccentric device (or control) for driving the dividers back and forth with respect to the inner casing. The eccentricity of the eccentric device corresponds with the eccentricity of the eccentric part of the power shaft. The eccentric device has a guide groove which implements an eccentric path and to which the dividers are connected.

The invention discloses a small soil stirring device which is easy to clean, comprising a strip-shaped support frame, a stirring and cleaning mechanism is provided on the upper surface of the strip-shaped support frame, and a limiting support mechanism is provided on the lower surface of the strip-shaped support frame. The beneficial effect of the present invention is that it is a device that is more convenient to use, has a relatively simple structure, and is more uniform in stirring, and is also convenient for more effective cleaning of the stirring tool after stirring, reduces labor intensity, has good sealing contact with the ground, and is relatively convenient to carry .

The invention discloses an electric fuel pump for an automobile. The electric fuel pump for the automobile comprises a pump case, a pump head component, a back cover component, an electric motor component installed inside the pump case, and a pump body component. The pump head component comprises a pump cover made of a plastic material, an anode insertion piece and a cathode insertion piece that are fixed on the pump cover. The anode insertion piece and the cathode insertion piece run through the upper end face and the lower end face of the pump cover, wherein a sealing ring is fixedly sleeved on the lower-half periphery of the connected portion among the anode insertion piece, the cathode insertion piece and the pump cover, with the lower end of the sealing ring being away from the lower end face of the pump cover by a certain distance. The anode insertion piece, the cathode insertion piece, the sealing ring and the pump cover are integrally injection molded. With the electric fuel pump for the automobile, the problem of leaking the fuel inside the fuel pump from the surfaces of the anode insertion piece and the cathode insertion piece can be thoroughly solved, thereby ensuring the safety of driving.

A flow control device for a heat exchanging system comprises a shell, a valve element and a transmission element; the shell forms a containing part, a first connection port and a second connection port; the valve element comprises a body part, a first circulating channel and a sealing contact part; the first circulating channel comprises at least one circulating port which outwards penetrates thebody part; the valve element can move relative to the shell; the first connection port and the second connection port can be connected through the first circulating channel; the sealing contact part and the inner periphery side of the shell are in movable sealing arrangement; the inner periphery side of the shell is provided with the shell contact part making contact with the sealing contact part;and the inner sealing performance of the product is improved.

The invention relates to a feed-through member (1) which is to be mounted in a wall element or floor element and comprises a tube element (2) that includes a first (23) and a second (24) tube element section. Said tube element sections (23, 24) can be moved relative to one another in the conducting direction (21) in such a way that the length of the tube element (2) is adjustable, a blocking mechanism (26, 32; 51, 61) being provided which at least partly prevents the tube element sections (23, 24) from moving when same are in the relative positions.
