DE20312257U1 - Rotary motor has two intermeshing cog-shaped pistons within two overlapping adjacent circular combustion chambers - Google Patents

Abstract

A rotary piston engine has a combustion chamber or pumping chamber consisting of two overlapping circular chambers with an intermeshing rotary piston at the center of each chamber (D, E). The cylinder has an inlet (F) and an outlet G) The pistons are especially essentially modified cogs. One rotary piston has two opposing wings and transmits power. The second piston is circular with two opposing grooves and prevents escape of expanding gases.

Description

The toothed piston rotor

This is a working machine or power machine. It can therefore be used both as a drive unit and as a pump.

The principle is based on the rotary piston process.
The special feature is based on the following characteristics:

1. The use and arrangement of the two modified gears

2. The parallel arrangement of the two work spaces.

The advantage of this invention lies - in addition to the usual advantages of rotary pistons (compared to oscillating pistons: little energy loss due to mass movement and favorable leverage in power transmission; compared to turbomachines: high efficiency in the low speed range and high pressure) - in continuous power transmission in every position of the rotor. The toothed piston rotor is particularly advantageous in the low speed range, where high torque is also required. As a pump, it can generate high pressure. The toothed piston rotor can also be used as a power transmission element. Its use could play a role, for example, in machines that work pneumatically or hydraulically with rotary movements (e.g. drills).

The toothed piston rotor is similar to the invention registered under JPOO5513999IAA, but differs from it by a continuous pressure transmission through the use of only one modified gear as a sealing element (marked by Fig. 1: E) and the use of two parallel working spaces (marked by Fig. 1: Ib: B, Fig. 2 and Fig. 3: Dl and D2)

The principle is based on two modified gears (mZ), one of which (Fig. 1: D) has two opposing teeth and the other (Fig. 1: E) has two opposing notches. Both mZ are coupled to each other with two gears (in a ratio of 1.1) outside the working area (Fig. Ib: A) in such a way that the two teeth

(within the working area) of one mZ (Fig. 1: D) engage in the notches of the other mZ (Fig. 1: E) during rotation. The mZ in Fig. 1: E fulfils the task of sealing the working area and preventing the pressure from escaping. The outer edge of this mZ is tightly but movably connected to the inner edge of the housing (Fig. 1: C). The outer edge of the teeth of the mZ (Fig. 1: D) is also tightly connected to the inner edge of the housing. The contact of the two mZs with each other at any time during rotation also forms a tight but movably seal.

View Ib shows a second working unit of the same design, but in which the teeth/notches are arranged at right angles to the first. The reason for this is described below.

The function (as a drive unit) results from the torque (see arrows H Fig. 1) exerted by the pressure of the working fluid (see arrow F Fig. 1:) on the "tooth piston" of the mZ (Fig. 1: D). When the first tooth piston passes the outlet opening G (Fig. 1), it engages in the notch of the mZ (Fig. 1: E). At the same time, the second tooth piston takes over the drive and thus also transports the remaining working fluid out.

The critical phase in which the mZ (D) is in the position shown in Fig. 3 (black mZ: Dl) leads to unstable running or to the system coming to a standstill, particularly in the low speed range in which the kinetic energy of the rotation does not provide enough momentum to drive the mZ past the inlet opening. In this phase, the torques (indicated by the double arrow G) cancel each other out because they act simultaneously in a clockwise and anti-clockwise direction.

This problem is solved by connecting a second working unit in parallel at an angle of 90 degrees to the first (see Fig. 2 and 3). Since the second mZ (see Fig. 3: D2) is in a more favorable position at this time, it can be driven by the working fluid acting there and keeps the system in continuous motion (see hatched arrow B in Fig. 3).

Claims (2)

1. Rotary piston working and power machine. It is characterized by the use of two modified gears, one of which ( Fig. I: D) has two opposing teeth and the other two opposing notches ( Fig. 1: E). Both mesh with each other and are located in a housing that resembles an "8" ( Fig. 1b: B) and has an inlet and an outlet opening ( Fig. 1: G, F). The power is transmitted via the modified gear with the two teeth. The modified gear with the two notches has the task of preventing the pressure from escaping. 2. Rotary piston working and power machine according to claim 1, characterized in that two working chambers are arranged in parallel and connected by two shafts in which the modified gears are at an angle of 90 degrees to each other in order to ensure a continuous drive ( Fig. 2).
