Embodiment Construction

[0009] Such as figure 1 As shown, the suspended piston cylinder assembly described in the embodiment of the present invention includes a cylinder 1, a piston 2 and a closed crankcase 3, the crankcase 3 is docked with the cylinder 1 and sealed, and the piston 2 is connected to the inner wall of the cylinder 1 There is a clearance fit between the cylinder 1 and the piston 2 for sliding sealing without a sealing ring. A gas backfilling pipeline 4 is connected to the side wall of the crankcase 3, and the gas backfilling pipeline 4 is connected to the cylinder 1 correspondingly. The position below the top dead center of the piston; a cooling fluid inlet 5 is provided on the side wall of the cylinder 1, and the cooling fluid inlet 5 communicates with a high-pressure cooling fluid container 6 and is provided with a control valve on the passage, and the cooling fluid inlet 5 is located on the side wall of the cylinder corresponding to the area between the top dead center and the botto...

Abstract

The invention discloses a suspension piston type cylinder component, which comprises a cylinder, a piston and a closed crankcase. The crankcase is in butt joint and sealed with the cylinder, the piston is in clearance fit with the inner wall of the cylinder, the cylinder is in sliding seal with the piston without a sealing ring, a gas recharge pipeline is connected onto a side wall of the crankcase, is connected onto the cylinder and corresponds the position below a top dead center of the piston, a cooling liquid inlet is arranged on a side wall of the cylinder and communicated with a high-pressure cooling liquid container via a channel, a control valve is disposed on the channel, and the cooling liquid inlet is positioned on the side wall of the cylinder and corresponds to an area between the top dead center and a bottom dead center of the piston. The suspension piston type cylinder component has the advantages that leaking gas of the suspension piston can be recharged into the cylinder via the gas recharge pipeline without leaking to the outside of a closed space encircled by the cylinder and the crankcase, so that burning high-pressure gas is sufficiently utilized assuredly.

Description

technical field [0001] The invention relates to a suspended piston type cylinder assembly, which belongs to the field of power system engines. Background technique [0002] As we all know, the cylinder and the piston in the existing cylinder-piston mechanism are all sealed and matched, and the outside of the piston is provided with 3-5 ring seals, which are in sealing and sliding contact with the inner wall of the cylinder, so that the piston can be kept in place when sliding in the cylinder. The gas inside the cylinder will not leak out. However, when the cylinder-piston mechanism is at high temperature, the various properties of the metal will decrease, including the friction resistance. Obviously, this will cause the cylinder inner wall of the cylinder-piston mechanism to wear under high temperature conditions. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the wear resistance of the prior art cylinder-piston mechan...
