SU1495471A1 - Face seals system for rotary-piston machine - Google Patents

Abstract

The invention relates to the design of units for rotary-piston machines, mainly heat engines. The purpose of the invention is to increase the tightness of the working cavities of the machine. The sealing system contains mechanical seal plates located in the rotor-piston, the main sealing pin, the annular oil seal and the radial strips in contact with the sealing pin and the oil seal. An additional pin is installed between the main sealing pin and the end plate, provided in the contact zone with the main pin, and with the end plate - with a notch to accommodate the end of this plate. The oil seal is in the form of a continuous ring. The elements of the sealing system form sections that seal the corresponding cavities of the machine. Thus, each pair of pins, end plates, radial strips, and part of the ring oil seal form a closed section that eliminates leakage of the working fluid into the body cavity. 2 hp f-ly, 3 ill.

Description

The invention relates to a rotary-rotary-rotary machine. M with planes by the movement of a rotor-piston in a working chamber, mainly to thermal engines. / The purpose of the invention is an increase in the tightness of the working cavities.

A rotor-pintle machine with a planetary movement of the rotor — pore shn in a trochannel working chamber made in housing 1 — contains a rotor-piston 2 mounted on the eccentric of the output shaft 3. For feeding and discharging the working fluid in the output shaft 3 and the rotor piston 2 has an axial and radial groove system connected on one side with a high pressure source (combustion chamber) and a lecturer.

The rotor piston 2 is equipped with cni.

The system works as follows.

During the operation of the maine, the working medium with high parameters enters the cavities of irreplaceable volume, formed by the surfaces of the working chamber and rotor pan, and there is a pressure drop there that drives the output shaft in, noc. Ie what enters the exhaust manifold. Radial and face seal systems prevent the flow of working fluid to form a section, ensuring sealing of the corresponding cavities. Thus, each pair of pins 5 p 8, end plates 4, radial n chank 7 and part of the oil seal fi form a closed section, and the mouth of the working fluid is installed into the hull of the case.
